Question

Jacob cuts a piece of cake into equal 12 slices on his birthday. His friends and others eat 10 of the slices. What fraction of the cake is left now?

Answer 1

Total number of equal slices of the cake $=12$

Number of equal slices eaten by Jacob's friends and others $=10$

Total number of slices left $=12-10=2$

Fraction of the cake left now = $\frac{2}{12}=\frac{1}{6}$

Thus, $\frac{1}{6}$th fraction of the cake is left.
