OpenStudy (♪chibiterasu):

You have to convert he mixed numbers into fractions, multiply and then simplify.

OpenStudy (♪chibiterasu):

\[\frac {10}{3} \times \frac {8}{7} = \frac {88}{21}\]

OpenStudy (♪chibiterasu):

Now we simplify. Woops.

OpenStudy (♪chibiterasu):

\[\frac {80}{21}\]

OpenStudy (♪chibiterasu):

21 goes into 8 three times. 3 21 * 3 = 63 What do we have left? 80 - 63 = 17 \[3 \frac{17}{21}\]
