Question

Divide 36 into two parts in such way that 1/5 of the one part is equal to 1/7of the other.

Answer 1

Answer: 15, 21

Step-by-step explanation:

Let one part be x

Let the second part be 36 - x

1/5 x = 1/7 (36 - x)

1/5 x = 1/7(36) - 1/7 x

1/5 x = 36/7 - 1/7 x

1/5 x + 1/7 x = 36/7

12/35 x = 36/7

x = 36/7(35/12) [division]

x = 15

So, one number is 15(x)

and the other number is 21(36-x)
