Paul has 75 fliers to post around town. Last week, he posted 2/5 of them. This week, he posted 1/5 of the remaining fliers. How many fliers has he still not posted?

He has not posted 30 of them.

Step-by-step explanation:

To find this amount, we first can note that he has not posted 2/5 of the fliers. We can find this by subtracting the two fractions that he has posted from the one whole.

1 - 2/5 - 1/5 = 2/5

Now we can multiply 2/5 by the number of fliers to find how many he hasn't posted.

2/5 * 75 = 30

30 fliers remaining

Step-by-step explanation:

2/5 + 1/5 = 3/5

5/5 - 3/5 = 2/5

2/5 of 75 = 30
