Simple math

C. Find common denominator, and subtract the numerators

However, you need to change the numerator to when you change the denominator.

Example,

2/3 - 1/2

find common denominator of 2 and 3

that will be 6

change numerator by dividing CD to denominator and multiplying numerator by the result.

so numerator of 1/2 will be (6 / 2) * 1 = 3

therefore

1/2 will be 3/6

and

2/3 will be 4/6

then subtract numerator

4 - 3 = 1

therefore

2/3 - 1/2 = 1/6

I hope it helps
