Question

There was 4/5 of a cake sitting on the counter. Daryl ate 1/3 of the left over cake. How much cake was left over after he ate?

Answer 1

7/15

Explanation:

4/5 - 1/3. Change the denominators to 15, do they same to the numerators which is multiply by 5. You then have 12 minus 5 = 7. So 7/15.

Answer 2

7/15

Explanation:

find a common demonator for example 15

you would do 4x3 for 12 and 5x3 for 15 so your first fraction would be 12/15

for the second fraction you will do 1x5 and 3x5 so your fraction would be 5/15

then you just subtract.
