hodyreva [135]

Answer:

$1\frac{7}{15}$

Step-by-step explanation:

The computation of the water did Audrina drink altogether is as follows:

$= \frac{4}{5} + \frac{2}{3}\\\\= \frac{12 + 10}{15} \\\\= \frac{22}{15}$

Now in a mixed fraction, it would be

$1\frac{7}{15}$

Hence, the water did Audrina drink altogether is $1\frac{7}{15}$
