32 + 5 × 22
= 9 + 5 × 4
= 9 + 20
= 29
Explanation:
The given expression is 32 + 5 × 22. First Perform the operation on square of the given numbers. Now the expression is 9 + 5 × 4. Multiply 5 with 4 the product is 20. Add 9 with 20 the sum is 29.

Question 7.
144 ÷ 12 = 3 ×
144 ÷ 12 = 3 ×
12 = 12
Explanation:
Divide 144 by 12 the quotient is 12. In order to get 12 we have to multiply 3 with 4 the product is 12. Both left side expression and right side expression are equal.

Question 8.
Find h.
$$\frac{64}{h}$$ = 16
h = _________
$$\frac{64}{h}$$ = 16
64 = 16 × h
64/16 = h
4 = h
Explanation:
To calculate h value we have to perform division operation. Divide 64 by 16 the quotient is 4. The value of h is equal to 4.

Question 9.
How many liters are in 7,500 milliliters?
Liter to milliliter conversion:
1 liter = 1,000 milliliters
1 × 1,000 = 1,000
Milliliters to liter conversion:
1 milliliter = 0.001 liter
1/1,000 = 0.001
There are 7.5 liters in 7,500 milliliters.
Explanation:
Multiply 7,500 milliliters with 0.001 the product is 7.5 liters. There are 7.5 liters in 7,500 millimeters.

Question 10.
How many vertices are on the square?

There are 4 vertices on the square.
Explanation:
In a square all four sides and all four angles are equal. The angles of the square is equal to 90-degrees.
Number of sides = 4
Number of vertices = 4
Area = Side2
Perimeter = 4(Side)

Question 11.
Two red blocks, two green blocks, and three yellow blocks were put into a bag. What is the probability that you will pull out a red or a green block?
Red blocks = 2
Green blocks = 2
Yellow blocks = 3
Total number of blocks in a bag = 2 + 2 + 3 = 7
Red blocks + green blocks = 4
The probability to pull out a red or a green block is 4/7.

Question 12.
Circle the factors of the given product.

 Possible Factors Product 8 2 6 3 5 4 12 10 21 124

Explanation:
Given the possible factors of the product 124 is 8, 2, 6, 3, 5, 4, 12, 10, 21, 124.
The factors of 124 are 1, 2, 4, 31, 62, 124.
The factors for the given product 124 is 2, 4. So drawn a circle for the factors 2 and 4 as we can observe in the above image.
