Zoe rides her bike $\frac{7}{10}$ mile to the grocery store. She then rides $\frac{1}{5}$ mile to her friend’s house. Zoe says she rode $\frac{8}{15}$ mile in all.

Which **two** statements are true?

A

Since $\frac{7}{10}$ plus $\frac{1}{5}$ is $\frac{1}{5}$, the total of $\frac{8}{15}$ is reasonable.

B

Since $\frac{8}{15}$ is less than $\frac{7}{10}$, the total of $\frac{8}{15}$ is not reasonable.

C

The fractions $\frac{8}{15}$, $\frac{7}{10}$ and $\frac{1}{5}$ are all less than $\frac{1}{2}$, so the total of $\frac{8}{15}$is reasonable.

D

The fraction $\frac{8}{15}=\frac{16}{30}$, and the fraction $\frac{7}{10}=\frac{21}{30}$, and $\frac{16}{30}$ is less than $\frac{21}{30}$, so the answer of $\frac{8}{15}$ is not reasonable.

E

Since $\frac{7}{10}$ and $\frac{1}{5}$ are each less than $\frac{8}{15}$, the answer $\frac{8}{15}$ is reasonable.
