Answer:
1. 1/4
2. 1/2
Step-by-step explanation:
1. Without measuring I can't be 100% sure, but it looks like the smaller rectangle is 1/4 of the big rectangle, as the side lengths of the smaller rectangle are half those of the big rectangle.
2. If he delivered 3/8 of his newspapers in the first hour, then he had:
1 - 3/8 = 5/8 of his newspapers left to deliver after the first hour.
If he delivered 4/5 of the remaining newspapers in the second hour:
4/5 ths of 5/8 = 4/5 x 5/8 = 20/40 = 1/2
He delivered 1/2 of all the newspapers in the second hour
