The denominator of a fraction is 9 more than the numerator. if both the numerator and the denominator are decreased by 1 the resulting fraction is equivalent to 4/13. find the fraction.

Respuesta :

x/x+9 (original fraction)

x+1/ x+10 = 4/13

x+1=4 so x=3 and x+10=13 so again x=3

now that you have the value of x, substitute it into the original fraction to get:

3/12
