Question

the numerator of a fraction is 8 less than its denominator. If 2 is added to both numerator and denominator,
fraction becomes 11/19. what should be fraction ?​

Answer 1

Step-by-step explanation:

let the common multiple be 'x'

denominator=x

numerator= x-8

x-8/x

If

2 is added on both sides.

then the new denominator =x+2

new numerator=x-8+2

=x-6

new fraction,

x-6/x+2

According to given condition,

x-6/x+2=11/19

19(x-6)=11(x+2)

19x-114=11x+22

19x-11x=22+114

8x=136

x=136/8

x=17

denominator = 17

numerator=x-8

=17-8

=9

therefore,

fraction=17/9
