Answer:
1. 6/15, or 2/5.
2. Apples cost more per pound.
Explanation:
1. Brian reads 2/15 in 20 minutes, like we were told. It's easy to determine how much of his book he can read within an hour, by using the ratio 1/15:10. There's clearly 1/15 in 10 minutes, 2/15 in 20, 3/15 in 30, and so on. This would result in him reading 6/15's of his book in an hour.
2.
Peaches
0.6÷8/5 converts to .6 × 5/8. The result is .375.
Apples
1.75 ÷7/2 converts to 1.75×2/7. The result of this equation is .5, so therefore, the apples cost more per pound.
