Answer:
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
