Answer 1

Jerry walked for 2/5 hours to the train station and the whole way took him 3 4/5 hours, then he had to go by bus

$3\dfrac{4}{5} -\dfrac{2}{5}$ hours.

First consider fractions $\dfrac{4}{5}$ and $\dfrac{2}{5}$. Subtracting from first fraction second fraction you have:

$\dfrac{4}{5} -\dfrac{2}{5}=\dfrac{4-2}{5} =\dfrac{2}{5}$.

Then add to the whole number this fraction and get

$3+\dfrac{2}{5} =3\dfrac{2}{5}$ hours.

Answer: Jerry spent riding on the bus $3\dfrac{2}{5}$ hours.
