Example 1.
A shopkeeper cut 30 m long cloth into 1 \(\frac {2}{ 8} \) each. Find the total number of pieces he cut?
Solution:
Length of the cloth=30 m
Each piece length =1\(\frac {2}{ 8} \) =\(\frac {10}{ 8} \)
The total number of pieces=30 ÷ \(\frac {10}{ 8} \)
=\(\frac {30}{ 1} \) ÷ \(\frac {10}{ 8} \)
=30 × \(\frac {8}{ 10} \)
=\(\frac {240}{ 10} \)Â =24
Anish cut the cloth into 24 pieces.
Example 2.
A board was 6 \(\frac {1}{ 5} \) feet long. It is cut into pieces 1 \(\frac {1}{ 3} \)Â feet long. Find how many pieces are there?
Solution:
The length of the board = 6 \(\frac {1}{ 5} \)
Each piece length = \(\frac {11}{ 3} \)
No. of pieces=6 \(\frac {1}{ 5} \) ÷1 \(\frac {1}{ 3} \)
=\(\frac {31}{ 5} \) ÷ \(\frac {4}{ 3} \)
=\(\frac {31}{ 5} \) × \(\frac {3}{ 4} \)
=\(\frac {93}{ 20} \) = 4 \(\frac {13}{ 20} \)
Hence, a board was cut into 4 \(\frac {13}{ 20} \)Â pieces.
Example 3.
Anusha is painting sarees. She has 1 \(\frac {1}{ 4} \) paint remaining. Each saree requires \(\frac {1}{ 10} \) of a liter of paint. How many sarees can she paint?
Solution:
Paint remaining=1 \(\frac {1}{ 4} \) =\(\frac {5}{ 4} \)
Each saree requires paint=\(\frac {1}{ 10} \)
No. of sarees she can paint= \(\frac {5}{ 4} \) ÷\(\frac {1}{ 10} \)
=\(\frac {5}{ 4} \) ×\(\frac {10}{ 1} \)
=\(\frac {50}{ 4} \)
=\(\frac {25}{ 2} \) = 12 \(\frac {1}{ 2} \)
Therefore, Anusha can paint 12 \(\frac {1}{ 2} \) sarees.
Example 4.
Charan bought 2 \(\frac {3}{ 5} \)Â kg chocolates and ate them in 20 days. How much did he consume each day?
Solution:
Charan bought chocolates= 2 \(\frac {3}{ 5} \) kg
Charan ate chocolates=20 days
Charan ate chocolates every day=2 \(\frac {3}{ 5} \) ÷ 20
=\(\frac {13}{ 5} \) ÷ 20
=\(\frac {13}{ 5} \) ×\(\frac {1}{ 20} \)
=\(\frac {13 ×1}{ 5 × 20} \)
=\(\frac {13}{ 100} \)
Therefore, Charan consumed \(\frac {13}{ 100} \) chocolates every day.
Example 5.
Suman reads \(\frac {1}{ 4} \) part of the book in 1 \(\frac {1}{ 6} \) hours. How much time will he need to complete the whole book?
Solution:
Suman reads \(\frac {1}{ 4} \) part of the book in hours= 1 \(\frac {1}{ 6} \)=\(\frac {7}{ 6} \)
The time needed to complete the whole book=\(\frac {7}{ 6} \) ×4=\(\frac {28}{ 6} \)
Suman needs \(\frac {28}{ 6} \) hours to complete the whole book.
Example 6.
Hasini has 1 \(\frac {3}{ 5} \) of a bag full of chips. She eats \(\frac {1}{ 4} \) of a bag for a week. How many weeks will the food last?
Solution:
Hasini has a bag full of chips= 1 \(\frac {3}{ 5} \)=\(\frac {8}{ 5} \)
Hasini eats chips in a bag for a week=\(\frac {1}{ 4} \)
No. of weeks will the food last=\(\frac {8}{ 5} \) ÷\(\frac {1}{ 4} \)
=\(\frac {8}{ 5} \) × \(\frac {4}{ 1} \)
=\(\frac {32}{ 5} \)
Therefore, food will last in \(\frac {32}{ 5} \) weeks.
Example 7.
Sarita has some cakes she wants to distribute. she is going to distribute each person \(\frac {1}{ 4} \) of a cake, and she has 4 \(\frac {2}{ 7} \) cakes to give away. How many people will get cake?
Solution:
Sarita will distribute cake for each person=\(\frac {1}{ 4} \)
No. of cakes Sarita has= 4 \(\frac {2}{ 7} \)
No. of people will get cake= 4 \(\frac {2}{ 7} \) ÷ \(\frac {1}{ 4} \)
=\(\frac {30}{ 7} \)÷ \(\frac {1}{ 4} \)
=\(\frac {30}{ 7} \) × \(\frac {4}{ 1} \)
=\(\frac {120}{ 7} \) =17 \(\frac {1}{ 7} \)
Therefore, Sarita will distribute the cakes to 17 \(\frac {1}{ 7} \).
Example 8.
The product of two numbers is 2 \(\frac {3}{ 16} \). If one of them is 1 \(\frac {7}{ 8} \).Find the other number?
Solution:
Product of two numbers=2 \(\frac {3}{ 16} \)=\(\frac {35}{ 16} \)
One of the number =1 \(\frac {7}{ 8} \)=\(\frac {15}{ 8} \)
Other number=\(\frac {35}{ 16} \) ÷\(\frac {15}{ 8} \)
=\(\frac {35}{ 16} \) ×\(\frac {8}{ 15} \)
=\(\frac {35 × 8}{ 16 × 15} \)
=\(\frac {280}{ 240} \)= \(\frac {7}{ 6} \)= 1\(\frac {1}{ 6} \)
Therefore, the other number is 1\(\frac {1}{ 6} \).
Example 9.
Harish has 1 \(\frac {7}{ 9} \) of the money. He spends \(\frac {1}{ 4} \) of the money for a week. In how many weeks will the money be spent?
Solution:
Harish has money=1 \(\frac {7}{ 9} \)=\(\frac {16}{ 9} \)
Harish spends money for a week=\(\frac {1}{ 4} \)
The money will be spent=\(\frac {16}{ 9} \)÷ \(\frac {1}{ 4} \)
=\(\frac {16}{ 9} \)× \(\frac {4}{ 1} \)= \(\frac {64}{ 9} \)= 7\(\frac {1}{ 9} \)
The money will be spent in 7\(\frac {1}{ 9} \) 1/9 weeks.
