10)

4 times a number is 24. Find the number.

Answer:_______________

9 times a number is 27. Find the number.

Answer: 3

SOLUTION 1 :

Let the requried number be y.

Given:

9y = 27

$\frac{9y}{9}$ = $\frac{27}{9}$ ( dividing both the sides by 9 ).

⇒ y = 3.

Hence, the requried number is 3.

3 times a number is 24. Find the number.

Answer: 8

SOLUTION 1 :

Let the requried number be x.

Given:

3x = 24

$\frac{3x}{3}$ = $\frac{24}{3}$ ( dividing both the sides by 3 ).

⇒ x = 8.

Hence, the requried number is 8.

7 times a number is 42. Find the number.

Answer: 6

SOLUTION 1 :

Let the requried number be y.

Given:

7y = 42

$\frac{7y}{7}$ = $\frac{42}{7}$ ( dividing both the sides by 7 ).

⇒ y = 6.

Hence, the requried number is 6.

6 times a number is 30. Find the number.

Answer: 5

SOLUTION 1 :

Let the requried number be x.

Given:

6x = 30

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

⇒ x = 5.

Hence, the requried number is 5.

6 times a number is 42. Find the number.

Answer: 7

SOLUTION 1 :

Let the requried number be x.

Given:

6x = 42

$\frac{6x}{6}$ = $\frac{42}{6}$ ( dividing both the sides by 6 ).

⇒ x = 7.

Hence, the requried number is 7.

2 times a number is 30. Find the number.

Answer: 15

SOLUTION 1 :

Let the requried number be y.

Given:

2y = 30

$\frac{2y}{2}$ = $\frac{30}{2}$ ( dividing both the sides by 2 ).

⇒ y = 15.

Hence, the requried number is 15.

4 times a number is 28. Find the number.

Answer: 7

SOLUTION 1 :

Let the requried number be y.

Given:

4y = 28

$\frac{4y}{4}$ = $\frac{28}{4}$ ( dividing both the sides by 4 ).

⇒ y = 7.

Hence, the requried number is 7.

5 times a number is 55. Find the number.

Answer: 11

SOLUTION 1 :

Let the requried number be x.

Given:

5x = 55

$\frac{5x}{5}$ = $\frac{55}{5}$ ( dividing both the sides by 5 ).

⇒ x = 11.

Hence, the requried number is 11.

5 times a number is 40. Find the number.

Answer: 8

SOLUTION 1 :

Let the requried number be x.

Given:

5x = 40

$\frac{5x}{5}$ = $\frac{40}{5}$ ( dividing both the sides by 5 ).

⇒ x = 8.

Hence, the requried number is 8.

10)

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.
