100% = 100, I know 31% of that is 31, but what I can't figure is 47% of 31, and I don't know how..
What is 64% of 47% of 31% of (I'm guessing) 100%?

31 % of 100 is 31 ... 47% of 31 is (47/100*31)=14.57 ... 64 % of 14.57 is (64/100*14.57) = 9.3248therefore your answer is 9.32

Work backwards. (i.e start with 31% of 100% which would be 31/100 x 100/100). That gives you 31%. Now keep going backwards, 47% of 31% = 47/100 x 31/100 = 1457/10000. Again go backwards, find 64% of 1457/10000....... 64/100 x 1457/10000 = 1457/15625. That in a decimal is approximately 0.093248. So the answer is, about 9.32%.

Hi!
Yes! There is an easy way. Remember that you can convert fractions to decimals like this
31% = .31
47% = .41
and so on. Now start with 100%, and multiply by .31. That will give you 31% of 100%.
100(.31)= 31
Now multiply 31 by .47
31(.47)= 14.57
Finally, multiply 14.57 by .64
14.57(.64)= 9.3248
And there's your answer! Hopefully that makes sense. Have a RAD day!

64% x 47% x 31% x 100%
= 64/100 x 47/100 x 31/100 x 100/100
= 16/25 x 47/100 x 31/100 x 1
= 752/2500 x 31/100
= 23312/250000
= 1457/15625
= 64/100 x 47/100 x 31/100 x 100/100
= 16/25 x 47/100 x 31/100 x 1
= 752/2500 x 31/100
= 23312/250000
= 1457/15625

64/100 x 47/100 x 31/100 x 100/100 =.0932=9.32%

31 % of 100 is 31 You know that
47 % of 31% of 100 = 0.47(31) = 0.1457 or 14.57 %
64 % of 47 % of 31% of 100 = 0.64(0.1457) = 0.0943248 = 9.43248 %
64 % of 47 % of 31% of 100 = 0.64(0.47)(0.31) = same answer as above
47 % of 31% of 100 = 0.47(31) = 0.1457 or 14.57 %
64 % of 47 % of 31% of 100 = 0.64(0.1457) = 0.0943248 = 9.43248 %
64 % of 47 % of 31% of 100 = 0.64(0.47)(0.31) = same answer as above

I think this question is tricky. Got to be careful and think clearly.
Firstly, remember that 31% means 31/100 which also basically means 31.
You see, by saying 47% of 31%, it means they want you to figure out how much is 47% out of 31. So, after calculating, you will get 14.57
Now, next step, do the same with 64%. Find 64% of 14.57
You will get 9.3248. Am I right?
ANSWER!!!
Hope this helps!
Ps: You can round it off anyway you want if you want to!
