Hello,

How can you explain in the most simple way (to a pupil age 10) what is 10% of 20% of 30% of 200?

Many thanks,

Natasha

I'd take it one step at a time.

First do 30% of 200. That get's you to 60.

Then do 20% of 60. That gives 12.

Then do 10% of 12. That gives 1.2

I wouldn't first multiply 10% * 20% * 30%. That's hard to understand. - Nov 21st 2009, 09:56 AMNatasha1

How would you go on to explain (again to the same child age 10) that the "

**of**", in 20%**of**80 is a multiplication sign?

Many thanks in advance
