Question

A cake is cut into $5$ equal parts. Robin gets $1$ of these parts. What fraction of the cake does Robin get?

• A. $\frac{4}{5}$
• B. $\frac{1}{5}$
• C. $\frac{5}{1}$
• D. $1$

Answer 1

The correct option is B $\frac{1}{5}$


The total number of parts the cake is divided into is the denominator: $5$
The number of parts that Robin gets is the numerator: $1$
So, the fraction of cake Robin got $=\frac{\text{Number of parts Robin gets}}{\text{Total number of parts of the cake}}=\frac{1}{5}$
