Ann had 45 fliers to post around town. last week, she posted 2/3 of them. this week, she posted 4/5 of the remaining fliers. how many fliers has she still not posted?

So, 1/3 of the posters were not originally posted. Then, 1/5 of the remaining 1/3 were not posted. So, 1/5 of 1/3 is 1/15. 45/15 = 3.

Step-by-step explanation:

She posted 2/3 of the 45 fliers last week, so there are 1/3 left. To know how much is 1/3 of 45, we just multiply them.

1/3 * 45 = 15

This week she posted 4/5 of the 15 fliers she had left, so she still not posted 1/5 of 15.

1/5 * 15 = 3

She still not posted 3 fliers.

207/8 is the right
