Question

On the next day, Nathan bought one whole chocolate pie and gave one-fourth part of it to her pet dog, Ollie. Ollie ate only one-fifth of that part. How much part of the pie did Ollie eat?

• A. $\frac{3}{25}$
• B. $\frac{1}{4}$
• C. $\frac{1}{20}$
• D. $\frac{4}{5}$

Answer 1

The correct option is C $\frac{1}{20}$

Fraction of the chocolate pie that Nathan gave to Ollie $=\frac{1}{4}$

Fraction of one-fourth part of the pie that Ollie ate $=\frac{1}{5}$

Fraction of the whole chocolate pie that Ollie ate $=\frac{1}{4}\times \frac{1}{5}=\frac{1}{20}$
