or 2.4

Here is a trick you should learn. When you have a problem like
\[ \frac{9}{10} \cdot \frac{8}{3} \]
Notice that both 9 in the top and 3 in the bottom can be divided by 3.
So do that immediately:
\[ \frac{\cancel{9}3}{10} \cdot \frac{8}{\cancel{3}1} \]
Also notice that 8 in the top and 10 in the bottom can be divided by 2
\[ \frac{3}{\cancel{10}5} \cdot \frac{\cancel{8}4}{1} \]
Now multiply to get
\[ \frac{12}{5} \]
As a mixed number (divide by 5 and write the remainder as a fraction)
\[ 2\frac{2}{5} \]
