Answer:_______________

5 times a number is 20. Find the number.

Answer: 4

SOLUTION 1 :

Let the requried number be y.

Given:

5y = 20

$\frac{5y}{5}$ = $\frac{20}{5}$ ( dividing both the sides by 5 ).

⇒ y = 4.

Hence, the requried number is 4.

9 times a number is 54. Find the number.

Answer: 6

SOLUTION 1 :

Let the requried number be x.

Given:

9x = 54

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

⇒ x = 6.

Hence, the requried number is 6.

7 times a number is 21. Find the number.

Answer: 3

SOLUTION 1 :

Let the requried number be x.

Given:

7x = 21

$\frac{7x}{7}$ = $\frac{21}{7}$ ( dividing both the sides by 7 ).

⇒ x = 3.

Hence, the requried number is 3.

4 times a number is 20. Find the number.

Answer: 5

SOLUTION 1 :

Let the requried number be y.

Given:

4y = 20

$\frac{4y}{4}$ = $\frac{20}{4}$ ( dividing both the sides by 4 ).

⇒ y = 5.

Hence, the requried number is 5.

8 times a number is 40. Find the number.

Answer: 5

SOLUTION 1 :

Let the requried number be x.

Given:

8x = 40

$\frac{8x}{8}$ = $\frac{40}{8}$ ( dividing both the sides by 8 ).

⇒ x = 5.

Hence, the requried number is 5.

5 times a number is 40. Find the number.

Answer: 8

SOLUTION 1 :

Let the requried number be y.

Given:

5y = 40

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

⇒ y = 8.

Hence, the requried number is 8.

8 times a number is 56. Find the number.

Answer: 7

SOLUTION 1 :

Let the requried number be y.

Given:

8y = 56

$\frac{8y}{8}$ = $\frac{56}{8}$ ( dividing both the sides by 8 ).

⇒ y = 7.

Hence, the requried number is 7.

7 times a number is 42. Find the number.

Answer: 6

SOLUTION 1 :

Let the requried number be x.

Given:

7x = 42

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

⇒ x = 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 y.

Given:

6y = 30

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

⇒ y = 5.

Hence, the requried number is 5.

10)

6 times a number is 60. Find the number.

Answer: 10

SOLUTION 1 :

Let the requried number be x.

Given:

6x = 60

$\frac{6x}{6}$ = $\frac{60}{6}$ ( dividing both the sides by 6 ).

⇒ x = 10.

Hence, the requried number is 10.
