Question

Tony cut his birthday cake into 6 equal slices his sister ate 1 slice and he ate 3 slices how many slices were left

Answer 1

Because he divided his cake into 6 equal pieces, we can represent the eaten and remaining amounts with fractions.

Remember that a fraction is the ratio of number of pieces over the total pieces.

So, we need to figure out how much cake needs to be subtracted.

We know his sister ate 1/6 of the cake and he ate 3/6 of the cake. We can add these fractions together because they have common denominators.

3/6+1/6=4/6

So, we need to subtract 4/6 from the whole:

6/6-4/6=2/6, so 2 slices out of the 6 remain.
