C! the product of them 2 is 9

Answer 2

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.
