Andrew, first find out how many pages he can write in 1 hour. Then multiply those numbers by 5.

Look at the numbers separately.

If he can write 3 pages in 2/3 of an hour, how many can he write in 1 hour?

The way to find out is to divide 3 by 2/3. When dividing by a fraction, it’s easier to multiply by the upside-down fraction. So,

3 / (2/3) = 3 * (3/2) = 9/2 pages per hour. Now multiply by 5 to see how many pages in 5 hours.

So that’s the result for 3 pages per 2/3 hour. Now try the same procedure for 4 pages in 2/3 hour.
