Answer:

10 [tex]\frac{1}{2}[/tex]

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 [tex]\frac{3}{4}[/tex] will be [tex]\frac{15}{4}[/tex] and 2 [tex]\frac{4}{5}[/tex] will be [tex]\frac{14}{5}[/tex]. now you multiply the numerator by the numerator and the denominator by the denominator. your fraction will be [tex]\frac{210}{20}[/tex]. to simplify, you divide 210 by 20 and you will get 10 [tex]\frac{1}{2}[/tex] :)
