Answer: D or 14
(24)/(25\\)

Explanation:

So this problem is actaully quite simple heres the first step

I just put the whole number into the fraction


4(2)/(5) *3(2)/(5)=((4*5)+2)/(5) *((3*5\\)+2)/(5)

Next we simplify the tops of the fractions.


((4*5)+2)/(5) *((3*5)+2)/(5)=(22)/(5) *(17)/(5)

Then we multiply


(22)/(5) *(17)/(5) =(22*17)/(5*5)

We finish multiplying


(22*17)/(5*5) =(374)/(25)

Hmm this could be close

374 is roughly 375 so...


(375)/(25) -(1)/(25) \\or\\(350)/(25) +(24)/(25)

This is better 350 is divisible by 25

in fact it is = 14 so the answer is


14(24)/(25)
