Question

Cosmo cuts 12 slices from a full cake, out of which 7 slices are eaten by Carla and her friends. What is the fraction of cake left?

• A. $\frac{7}{12}$
• B. $\frac{3}{12}$
• C. $\frac{12}{7}$
• D. $\frac{5}{12}$

Answer 1

The correct option is D $\frac{5}{12}$

There are 12 slices of cake, out of which 7 slices are eaten by Carla and her friends.
Therefore, the remanining slices = 12 - 7
= 5

$\text{Fraction of cake left}=\frac{\text{Slices that are remaining}}{\text{Total number of slices}}$
$=\frac{5}{12}$
