Answer:

Option C

Explanation:

In order to find the answer to this question you need to convert the mixed numbers into improper fractions and then solve by means of multiplication.


4(1)/(5) *2(1)/(7)

Convert into improper fractions:


4(1)/(5) =5*4=20+1=(21)/(5)


2(1)/(7) =7*2=14+1=(15)/(7)


(21)/(5)*(15)/(7)

Multiply:


21*15=315


5*7=35


=(315)/(35)

Simplify:


315/5=63


35/5=7

Simplify once more:


63/7=9


7/7=1


=(9)/(1) =9


=9

Hope this helps.
