    Percentage question

    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

    One way among many

    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.

    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
