John and Maria had an 8 slice pizza. John ate 1/3 and maria ate 1/4. how much pizza was left?

1/3 + 1/4 = 4/12 + 3/12 = 7/12

12/12 - 7/12 = ?

1/8= 3/24= 1 slice

John 1/3= 8/24= 2 2/3 slices
Maria 1/4= 6/24= 2 slices

To find out how much pizza is left after John and Maria ate their share, we need to subtract the sum of their shares from the total number of slices.

First, let's calculate how many slices John ate: 1/3 * 8 slices = 8/3 slices.

Next, let's calculate how many slices Maria ate: 1/4 * 8 slices = 8/4 slices.

To add these fractions together, we need to find a common denominator, which is 12 in this case.

John's share as 12 slices: (8/3 slices * 4/4) = 32/12 slices.

Maria's share as 12 slices: (8/4 slices * 3/3) = 24/12 slices.

Now, let's calculate the sum of John's and Maria's shares: 32/12 slices + 24/12 slices = 56/12 slices.

To find out how much pizza is left, we subtract the sum of their shares from the total number of slices:

8 slices - 56/12 slices = 96/12 slices - 56/12 slices = 40/12 slices.

Therefore, there are 40/12 slices of pizza left.
