What is 5/6 of a pie minus 2/3 of a pie?

The expression for this is 5/6 - 2/3. First, we want to find the LCM of 6 and 3, which is 6, because we want to make both fractions have the same denominator

5/6 = 5/6

2/3 x 2/2 = 4/6

Now we can subtract 4/6 from 5/6, which is 1/6.

4/6 is the same as 2/3 so

5/6 - 4/6 = 1/6
