Question

divide 36 in two parts in such a way that 1/5 of one part is equal to 1/7 of the other

Answer 1

Step-by-step explanation:

The one part is 15 and another part is 21. Now we are give that that 1/5 of one part is equal to 1/7 of the other

Let first part be x,

And, second part = 36-x

Now, 1/5th of first part = 1x/5

And, 1/ 7th part of second part = 1 ( 36-x) / 7

According to question,

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

By cross multiplication,

7x = 180 - 5x

12x = 180

x = 180/12 = 15

Therefore, first part = x = 15

And, second part = 36-x = 36-15 = 21

Answer 2

Answer:

let the first part be x and the second part be 36-x

according to the question

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

x/5 = 36 - x/7

7 * x = 5 ( 36 - x)

7x = 180 - 5x

7x + 5x =  180

12x = 180

x = 15

first part = 15

second part = 21
