Directions: Solve each problem.

Question 1.
Take 63 away from 187.
Subtraction is one of the four basic arithmetic operations in mathematics. We can observe the applications of subtraction in our everyday life in different situations.  For example, when we purchase fruits and vegetables for a certain amount of money say Rs. 200 and we have been given Rs. 500 note to the vendor. Now, the vendor returns the excess amount by performing subtraction such as 500 – 200 = 300. Then, the vendor will return Rs. 300.
Now we need to calculate the above-given question: 187 = Minuend; 63 = Subtrahend; 124 = Difference

Question 2. In mathematics, multiplication is a method of finding the product of two or more numbers. It is one of the basic arithmetic operations, that we use in everyday life. The major application we can see in multiplication tables.
In arithmetic, the multiplication of two numbers represents the repeated addition of one number with respect to another. These numbers can be whole numbers, natural numbers, integers, fractions, etc. If m is multiplied by n, then it means either m is added to itself ‘n’ a number of times or vice versa.
The formula for multiplication:
The multiplication formula is given by:
Multiplier × Multiplicand = Product
– The multiplicand is the total number of objects in each group
– A multiplier is the number of equal groups
– Product is the result of multiplication of multiplier and multiplicand Question 3.
147 ÷ 13= ____________
The division is breaking a number into an equal number of parts. The division is an arithmetic operation used in Maths. It splits a given number of items into different groups.
There are a number of signs that people may use to indicate division. The most common one is ÷, but the backslash / and a horizontal line (-) are also used in the form of Fraction, where a Numerator is written on the top and a Denominator on the bottom.
The division formula is:
Dividend ÷ Divisor = Quotient (or) Dividend/Divisor=quotient therefore, the quotient is 11.3 and the remainder is 1.

Question 4.
What is the value of the digit 5 in the number 95,340?
Place value in Maths describes the position or place of a digit in a number. Each digit has a place in a number. When we represent the number in general form, the position of each digit will be expanded. Those positions start from a unit place or we also call it one’s position. The order of place value of digits of a number of right to left is units, tens, hundreds, thousands, ten thousand, a hundred thousand, and so on. Therefore, 5 is in the thousands place.

Question 5.
Simplify $$\frac{3}{6}$$
$$\frac{3}{6}$$ can be written as 3/6 3 is the greatest common divisor of 3 and 6. Reduce by dividing both numerator and denominator by 3.

Question 6.
25 + 80 ÷ 2 = __________
the value of 80 ÷ 2 is 40 Now add the number we got with 25. Let’s assume the answer is X.
x = 25 + 40
X = 65.
therefore, the answer for the above equation is 65.

Question 7. – 49 = 37
Let the empty box be X.
X – 49 = 37
Now get 49 to the right-hand side then the equation is:
X = 37 + 49
X = 86
Now substitute X value in the above equation.
X – 49 = 37
86 – 49 = 37
37 = 37
LHS = RHS

Question 8.
1$$\frac{1}{2}$$ hours = _________ minutes
1$$\frac{1}{2}$$ hours can be written as 1 1/2
1 1/2 hour is equal to X minutes
1 hour = 60 minutes
1/2 an hour = 1/2 x 60
1/2 an hour = 30 minutes.
1 1/2 hour = 60 + 30
1 1/2 hour = 90 minutes.

Question 9.
How many faces are there on a triangular pyramid?
A triangular pyramid is a pyramid that has a triangular base. In geometry, vertices are essentially corners. All triangular-based pyramids, either regular or irregular, have four vertices.
Properties of the triangular pyramid:
– The triangular pyramid has 4 faces
– The 3 side faces of the triangular pyramid are triangles
– The base is also triangular in shape
– It has 4 vertices (corner points)
– It has 6 edges
– Triangular pyramids can be regular, irregular and right-angled
– A regular triangular pyramid has equilateral triangles for all four faces. Question 10.
The rainfall for April last year was 52 mm. How much less rain was recorded in April in the graph below? The rainfall recorded in April = 35mm
The rainfall recorded last year in April  was 52mm
By comparing last year’s rainfall and the present gave rainfall how much less the rain was recorded we need to calculate. Assume it as X.
X = last year’s rainfall – present rainfall
X = 52 – 35
X = 17 mm
Therefore, 17 millimetres of rainfall is less were recorded.

Question 11.
You make trail mix using the following ingredients: 25 candies, 50 raisins, 75 pieces of cereal, and 50 peanuts. If you reach in the bowl and grab one piece of food, what is the probability you will grab a pretzel?

Question 12.
