Answer 1

Answer:

The numerator of a fraction is 3 less than its denominator if 2 added to both numerator and denominator . then new fraction is 6/7 , find original one.

let the numerator be X -3 and denominator is X

(x-3)+2/X+2=6/7

(x-3)+2=6

x-3=6-2

X=4+3

X=7

answer is 2/5

Answer 2

Answer:

let the numerator be x-3&denominator be x

=x-3/x

x-3+2/x+2=6/7

=2x-6+2x/2x=6/7, 7(4x-6)=12x

28x-12x=42

16x=42

x=42/16=21/8
