Question

1. Add the same number to both the numerator and the denominator of

the fraction 7/17, to change it to 3/5.​

Answer 1

8

Explanation:

Let x be the number added to both numerator and denominator.

Initial fraction=7/17

After adding x to both the numerator and the denominator

Then ,we get fraction=3/5

We have to find the value of x.

According to question

`(7+x)/(17+x)=(3)/(5)`

`5(7+x)=3(17+x)`

`35+5x=51+3x`

`5x-3x=51-35`

`2x=16`

`x=(16)/(2)=8`
