Question

How well do you know your fractions? If Maria has a cake with 8 slices and she eats 3 slices, what fraction of the cake is left?

Answer 1

Hey mate here's your answer

Total piece of cake = 8

Pieces eaten = 3

Pieces left = 8-3=5

Therefore, fraction = 5/8

Answer 2

$\bold{\frac{5}{8}}$ is the fraction of the cake left if Maria has 8 slices and she eats 3 slices.

Given:

Total slices of cake Maria has = 8  

Total slices she ate = 3

To find:

The fraction of the cake left =?

Solution:  

The total number of slices from the cake is 8, this will become the Sample Space, and the number of slices Maria ate was 3.

Therefore, the number of slices left = total number of slices – number of slices eaten by Maria

Number of slices left = 8 – 3 = 5

Hence, the number of slices left is 5.

To find the fraction of the cake left $=\frac{\text {total number of slices left}}{\text {total number of slices }}=\frac{5}{8}$

Therefore, the fraction of the cake left after eating 3 slices is $\bold{\frac{5}{8}.}$
