Question

Ramesh solved $\frac{2}{7}$ part of an exercise while Reshma solved $\frac{4}{5}$ of it. Who solved the lesser part. By how much

Answer 1

$\frac{2}{7}\times \frac{5}{5}=\frac{10}{35}$

$\frac{4}{5}\times \frac{7}{7}=\frac{28}{35}$

$\therefore \frac{28}{35}>\frac{10}{35}\Rightarrow \frac{4}{5}>\frac{2}{7}$

Now,

$\frac{4}{5}-\frac{2}{7}=\frac{28-10}{35}=\frac{18}{35}$

Hence Ramesh solved lesser part of the question by $\frac{18}{35}$ part.
