10)

4 times a number is 36. Find the number.

Answer:_______________

8 times a number is 32. Find the number.

Answer: 4

SOLUTION 1 :

Let the requried number be y.

Given:

8y = 32

$\frac{8y}{8}$ = $\frac{32}{8}$ ( dividing both the sides by 8 ).

⇒ y = 4.

Hence, the requried number is 4.

8 times a number is 24. Find the number.

Answer: 3

SOLUTION 1 :

Let the requried number be x.

Given:

8x = 24

$\frac{8x}{8}$ = $\frac{24}{8}$ ( dividing both the sides by 8 ).

⇒ x = 3.

Hence, the requried number is 3.

6 times a number is 30. Find the number.

Answer: 5

SOLUTION 1 :

Let the requried number be y.

Given:

6y = 30

$\frac{6y}{6}$ = $\frac{30}{6}$ ( dividing both the sides by 6 ).

⇒ y = 5.

Hence, the requried number is 5.

5 times a number is 30. Find the number.

Answer: 6

SOLUTION 1 :

Let the requried number be x.

Given:

5x = 30

$\frac{5x}{5}$ = $\frac{30}{5}$ ( dividing both the sides by 5 ).

⇒ x = 6.

Hence, the requried number is 6.

9 times a number is 45. Find the number.

Answer: 5

SOLUTION 1 :

Let the requried number be y.

Given:

9y = 45

$\frac{9y}{9}$ = $\frac{45}{9}$ ( dividing both the sides by 9 ).

⇒ y = 5.

Hence, the requried number is 5.

9 times a number is 54. Find the number.

Answer: 6

SOLUTION 1 :

Let the requried number be y.

Given:

9y = 54

$\frac{9y}{9}$ = $\frac{54}{9}$ ( dividing both the sides by 9 ).

⇒ y = 6.

Hence, the requried number is 6.

3 times a number is 36. Find the number.

Answer: 12

SOLUTION 1 :

Let the requried number be x.

Given:

3x = 36

$\frac{3x}{3}$ = $\frac{36}{3}$ ( dividing both the sides by 3 ).

⇒ x = 12.

Hence, the requried number is 12.

4 times a number is 24. Find the number.

Answer: 6

SOLUTION 1 :

Let the requried number be y.

Given:

4y = 24

$\frac{4y}{4}$ = $\frac{24}{4}$ ( dividing both the sides by 4 ).

⇒ y = 6.

Hence, the requried number is 6.

2 times a number is 20. Find the number.

Answer: 10

SOLUTION 1 :

Let the requried number be x.

Given:

2x = 20

$\frac{2x}{2}$ = $\frac{20}{2}$ ( dividing both the sides by 2 ).

⇒ x = 10.

Hence, the requried number is 10.

10)

4 times a number is 36. Find the number.

Answer: 9

SOLUTION 1 :

Let the requried number be x.

Given:

4x = 36

$\frac{4x}{4}$ = $\frac{36}{4}$ ( dividing both the sides by 4 ).

⇒ x = 9.

Hence, the requried number is 9.
