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

Answer:

8

Step-by-step 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

$\frac{7+x}{17+x}=\frac{3}{5}$

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

$35+5x=51+3x$

$5x-3x=51-35$

$2x=16$

$x=\frac{16}{2}=8$
