Problem 1:

Gita has eight marbles. She gave \(\frac { 1 }{ 4 } \) of them to her younger brother. How many marbles did her brother get?

Solution:

As given in the question,

Gita has marbles = 8

She gave to younger brother = \(\frac { 1 }{ 4 } \) of 8

No of marbles her brother got = \(\frac { 1*8 }{ 4 } \)

= \(\frac { 2 }{ 1 } \)

= 2

Therefore, her brother got 2 marbles

Thus, the final solution is 2 marbles


Problem 2:

Mr. Gupta puts 3\(\frac { 1 }{ 4 } \) litres of petrol in his car. If he uses \(\frac { 1 }{ 3 } \) of it. How many litres of petrol did he use?

Solution:

As given in the question,

Mr. Gupta puts = 3\(\frac { 1 }{ 4 } \) litres of petrol

He used = \(\frac { 1 }{ 3 } \) of 3\(\frac { 1 }{ 4 } \)

\(\frac { 1 }{ 3 } \) * \(\frac { 13 }{ 4 } \)

\(\frac { 1*13 }{ 3*4 } \)

3\(\frac { 13 }{ 12 } \)

1\(\frac { 1 }{ 12 } \)

Therefore, Mr. Gupta used 1\(\frac { 1 }{ 12 } \) litres of petrol.

Thus, the final solution is 1\(\frac { 1 }{ 12 } \) litres


Problem 3:

Neha spends 3\(\frac { 3 }{ 5 } \) hours a day in morning exercises. How many hours does she spend in morning exercises in one week?

Solution:

As given in the question,

Neha spends = \(\frac { 3 }{ 5 } \) hours/day

Hours she spends in a week = \(\frac { 3 }{ 5 } \) * 7

\(\frac { 3*7 }{ 5 } \) \(\frac { 21 }{ 5 } \)

4\(\frac { 1 }{ 5 } \) hours

Therefore, Neha spends 4\(\frac { 1 }{ 5 } \) hours in morning exercises.

Thus, the solution is 4\(\frac { 1 }{ 5 } \) hours


Problem 4:

One plum cake weighs \(\frac { 3 }{ 4 } \) kg. If Mr. Ramesh buys five such cakes, how many kilograms of cakes did he buy?

Solution:

As given in the question,

Weight of one plum cake = \(\frac { 3 }{ 4 } \) kg

No of cakes = 5

Amount of cake he bought = \(\frac { 3 }{ 4 } \) * 5

\(\frac { 3*5 }{ 4 } \) \(\frac { 15 }{ 4 } \)

Therefore, \(\frac { 15 }{ 4 } \) kilograms of cake, Mr. Ramesh buy

Thus, the final solution is \(\frac { 15 }{ 4 } \)


Problem 5:

The cost of one kilogram apples is Rupees 25\(\frac { 1 }{ 2 } \). What is the cost of 1\(\frac { 1 }{ 2 } \) kilogram apples?

Solution:

As given in the question,

The cost of one kilogram apple = 25\(\frac { 1 }{ 2 } \)

The cost of 1\(\frac { 1 }{ 2 } \) kilogram apples = 25\(\frac { 1 }{ 2 } \) * 1\(\frac { 1 }{ 2 } \)

\(\frac { 51 }{ 2 } \) * \(\frac { 3 }{ 2 } \)

\(\frac { 153 }{ 4 } \)

Therefore, \(\frac { 153 }{ 4 } \) is the price for 1\(\frac { 1 }{ 2 } \) kilogram apples.

Thus, the final solution is \(\frac { 153 }{ 4 } \)


Problem 6:

The thickness of the Mathematics book of Class – IV is 1\(\frac { 1 }{ 4 } \) cm. What will be the thickness of a pile of 16 such books?

Solution:

As given in the question,

Thickness of book = 1\(\frac { 1 }{ 4 } \)

No of books = 16

The thickness of a pile of 16 books = 1\(\frac { 1 }{ 4 } \) * 16

\(\frac { 5 }{ 4 } \) * 16

\(\frac { 80 }{ 4 } \)

= 20

Therefore, the thickness of a pile of 16 books is 20cm.

Thus, the final solution is 20cm.


Problem 7:

Milk is sold at Rs 16\(\frac { 3 }{ 4 } \) per litre, find the cost of 6\(\frac { 2 }{ 5 } \) litre of milk?

Solution:

As given in the question,

Cost of 1 litre milk = 16\(\frac { 3 }{ 4 } \)

Cost of \(\frac { 32 }{ 5 } \) litre milk = 16\(\frac { 3 }{ 4 } \)

= \(\frac { 67 }{ 4 } \)

The cost of 6\(\frac { 2 }{ 5 } \) is \(\frac { 67 }{ 4 } \) * \(\frac { 32 }{ 5 } \)

= \(\frac { 67*8 }{ 5 } \)

= \(\frac { 536 }{ 5 } \)

= 107\(\frac { 1 }{ 5 } \)

Therefore, the cost of 6\(\frac { 2 }{ 5 } \) litre of milk is 107\(\frac { 1 }{ 5 } \)

Thus, the final solution is 107\(\frac { 1 }{ 5 } \)


Problem 8:

Find the area of the rectangular park which is 41\(\frac { 2 }{ 3 } \) long and 18\(\frac { 3 }{ 5 } \) m board?

Solution:

As given in the question,

Length of the rectangular park = 41\(\frac { 2 }{ 3 } \)

Breadth of the rectangular park = 18\(\frac { 3 }{ 5 } \)

Area of rectangle = length * breadth

= \(\frac { 125 }{ 3 } \) * \(\frac { 93 }{ 5 } \)

= 775 meters

Therefore, the area of the rectangular park is 775 meters

Thus, the final solution is 775 meters.


Problem 9.
If the cost of 5\(\frac { 2 }{ 5 } \) litres of milk is 236\(\frac { 1 }{ 4 } \), find the cost per litre?

Solution:

As given in the question,

The cost of milk = 236\(\frac { 1 }{ 4 } \)

No of litres = 5\(\frac { 2 }{ 5 } \)

Cost of \(\frac { 27 }{ 5 } \) litres of milk = \(\frac { 945 }{ 4 } \)

Cost of 1 litre of milk = \(\frac { 945%4 }{ 27%5 } \)

= \(\frac { 945 }{ 4 } \) * \(\frac { 5 }{ 27 } \)

= \(\frac { 35*5 }{ 4 } \)

= \(\frac { 175 }{ 4 } \)

= 43\(\frac { 3 }{ 4 } \)

Therefore, the cost per litre = 43\(\frac { 3 }{ 4 } \)

Thus, the final solution is 43\(\frac { 3 }{ 4 } \)


Problem 10:

Margaret has 2\(\frac { 1 }{ 3 } \) cups of sugar. She is using 1\(\frac { 1 }{ 4 } \) cups to make cookies. How much sugar will she have left?

Solution:

As given in the question,

Amount of sugar Margaret has = 2\(\frac { 1 }{ 3 } \)

No of cups she is using to make cookies = 1\(\frac { 1 }{ 4 } \)

Amount of sugar will she have left = 2\(\frac { 1 }{ 3 } \) – 1\(\frac { 1 }{ 4 } \)

= \(\frac { 7 }{ 3 } \) – \(\frac { 5 }{ 4 } \)

= \(\frac { 7 }{ 3 } \) * \(\frac { 4 }{ 4 } \) – \(\frac { 5 }{ 4 } \) * \(\frac { 3 }{ 3 } \)

= \(\frac { 28 }{ 12 } \) – \(\frac { 15 }{ 12 } \)

= \(\frac { 28-15 }{ 12 } \)

= \(\frac { 13 }{ 12 } \)

Therefore, \(\frac { 13 }{ 12 } \) cups of sugar will she have left.

Thus, the final solution is \(\frac { 13 }{ 12 } \)


Problem 11:

Russell spent \(\frac { 1 }{ 3 } \) of his allowance to go to movies. He wants to buy a new video game that will cost him another \(\frac { 1 }{ 2 } \) of his allowance. If he buys the game. How much of his allowance will he have spent?

Solution:

As given in the question,

Amount of money Russell spent on movies = \(\frac { 1 }{ 3 } \)

Amount of money Russell spent on new video game = \(\frac { 1 }{ 2 } \)

Total amount of money he spent of his allowance = \(\frac { 1 }{ 3 } \) + \(\frac { 1 }{ 2 } \)

= \(\frac { 1 }{ 3 } \) * \(\frac { 2 }{ 2 } \) + \(\frac { 1 }{ 2 } \) * \(\frac { 3 }{ 3 } \)

= \(\frac { 2 }{ 6 } \) + \(\frac { 3 }{ 6 } \)

= \(\frac { 2+3 }{ 6 } \)

= \(\frac { 5 }{ 6 } \)

Therefore, the total amount of money spent = \(\frac { 5 }{ 6 } \)

Thus, the final solution is \(\frac { 5 }{ 6 } \)


Problem 12:

Sam has 3\(\frac { 1 }{ 8 } \) acres of land. He planted potatoes on 2\(\frac { 2 }{ 3 } \) of the land. He wants to plant corn. How much land does he have left to plant the corn?

Solution:

As given in the question,

Acres of land Sam has = 3\(\frac { 1 }{ 8 } \)

Acres of land he planted potatoes = 2\(\frac { 2 }{ 3 } \)

Amount of land left to plant the corn = 3\(\frac { 1 }{ 8 } \) – 2\(\frac { 2 }{ 3 } \)

= \(\frac { 25 }{ 8 } \) – \(\frac { 8 }{ 3 } \)

= \(\frac { 25 }{ 8 } \) * \(\frac { 3 }{ 3 } \) – \(\frac { 8 }{ 3 } \) * \(\frac { 8 }{ 8 } \)

= \(\frac { 75 }{ 24 } \) – \(\frac { 64 }{ 24 } \)

= \(\frac { 75-64 }{ 24 } \)

= \(\frac { 11 }{ 24 } \)

Therefore, \(\frac { 11 }{ 24 } \) acres of land left to plant the corn.

Thus, the final solution is \(\frac { 11 }{ 24 } \)


Problem 13:

I bought 80 pounds of spaghetti to share equally between 7 families. About how many pounds of spaghetti will each family receive?

Solution:

As given in the question,

Amount of spaghetti = 80 pounds

No of families = 7

Amount of spaghetti each family receive = \(\frac { 80 }{ 7 } \)

Therefore, \(\frac { 80 }{ 7 } \) pounds of spaghetti each family will receive.


Problem 14:

I have 70 feet of rope that I need to share equally between 11 people. About how many feet of rope will each person receive?

Solution:

As given in the question,

No of people = 11

Length of the rope = 70 feet

Length of rope each person will receive = \(\frac { 70 }{ 11 } \)

Therefore, each person will receive \(\frac { 70 }{ 11 } \) feet of rope.

Thus, the final solution is \(\frac { 70 }{ 11 } \).


Problem 15:

Mom made pizza. There is only \(\frac { 1 }{ 4 } \) of the pizza left. Mom and her friend Sally are going to share the remaining pizza evenly. How much of pizza will they each get?

Solution:

As given in the question,

Fraction of pizza left = \(\frac { 1 }{ 4 } \)

No of people who share the pizza = 2

Amount of pizza each will get = \(\frac { 1%4 }{ 2 } \)

= \(\frac { 1 }{ 4 } \) * \(\frac { 2 }{ 1 } \)

= \(\frac { 2 }{ 4 } \)

= \(\frac { 1 }{ 2 } \)

Therefore, each gets \(\frac { 1 }{ 2 } \) of pizza.

Thus, the final solution is \(\frac { 1 }{ 2 } \)
