Answer:
3/10
Step-by-step explanation:
If Addison livers 1/5 of the newspapers in the neighborhood and I need a delivers 1/2 of them, the total fraction of paper used will be;
1/5 + 1/2
= (2+5)/10
= 7/10
The fraction of the paper left = 1 - 7/10
The fraction of the paper left = (10-7)/10
The fraction of the paper left = 3/10
