Answer:
12/9
Step-by-step explanation:
Let the denominator be 'x'
therefore, numerator = x+3
original fraction = x+3/x
form the question, x+3+3/x-3
new fraction = x+6/x-3
Given that x+6/x-3 = 5/2
by cross multiplying,
2(x+6) = 5(x-3)
2x + 12 = 5x - 15
15 + 12 = 5x - 2x
27 = 3x
x = 27/3
x = 9
therefore denominator = 9 nad numerator = x+3 = 12
original fraction = 12/9
