Question

divide 12 in the ratio 1 :3.

Answer 1

Answer:

1st number = 3

2nd number = 9

Step-by-step explanation:

Let the numbers in the ratio 1 : 3 be 1x ie. x and 3x

Given, their sum is 12

According to the question,

x + 3x = 12

=> 4x = 12

=> x = $\dfrac{12}{4}$

=> x = 3

Dividing 12 in the 1st number i.e. x

=> 3

Dividing 12 in the 2nd number i.e. 3x

=> 3 * 3

=> 9

Verification :-

x + 3x = 12

=> 4x = 12

=> 4 * 3 = 12

=> 12 = 12

$\therefore{}$ LHS = RHS
