eXCUSE ME!!! I NEED HELP PRONTO!! BRAINLIEST PLS! in a fraction the denominator is 4 less than the numerator. If 3 is added to b
avanturin [10]

7/5 = 14/10 = 28/20

Numerator = x

Denominator = x-4

Add 3 to both:

x +3 / (x-4+3)

x+3 = 14

(x-4 +3) = 10 = x-1 = 10

x = 11

Check:

11 -4 = 7 ( denominator is 4 less than the numerator.)

add 3 to both:

11+3 = 14

7+3 = 10

14/10 reduces to 7/5

The original fraction would be 11/7
