Question

4. The sum of the numerator and the denominator
of a fraction is 9. If 3 is added to each of the numerator and the denominator, it becomes
1/2. Find the fraction.​

Answer 1

Step-by-step explanation:

Let's assume that

denominator = y, numerator = x

So their sum

x+y = 9

y = 9-x

and if 3 is added to both their fraction become

Cross multiple

2x +6 = y +3

putting value of y

2x +6 = (9-x) +3

2x +6 = 9 - X +3

2x +X = 12 +6

3x = 18

x = 18/3

x = 6

y = 9-x

so, y = 9-6

y = 3
