what is 10% of 20% of 30% pf 100?

100 * .30 = 30
30 * .20 = 6
6 * .10 = .6

I hope that's what your looking for!

Are these three separate questions?
10% = 0.10 x 100 = ??
20% = 0.20 x 100 = ??
30% = 0.30 x 100 = ??
Remember of means times.

Or is it just one question?
0.10 x 0.20 x 0.30 x 100 = ??

It sounds to me like it is just one question.
