Answer:

10 $\frac{1}{2}$

Step-by-step explanation:

to multiply, convert each fraction into an improper fraction. you do that by multiplying the denominator by the whole number and adding the numerator. so 3 $\frac{3}{4}$ will be $\frac{15}{4}$ and 2 $\frac{4}{5}$ will be $\frac{14}{5}$ . now you multiply the numerator by the numerator and the denominator by the denominator. your fraction will be $\frac{210}{20}$ . to simplify, you divide 210 by 20 and you will get 10 $\frac{1}{2}$ :)
