Question

An athlete pays 1/10 of her annual income to her agent.The agent pays 2/9 of that money to his assistant.What fraction of her annual income is the athlete paying the assistant?

Answer 1

You multiply the fractions like this:
1/10 * 2/9 = 2/90

Then you reduce it.

1/45

So 1/45 of the athlete's annual income is payed to the assistant.
