Question

It rained One and one-sixteenth inches on Saturday and 0.4 inches on Sunday. Which is the most reasonable estimate for the amount of rain that fell over two days?

0.5 inches

1.5 inches

2 inches

3 inches

Answer 1

Answer: 1.5 inches

Explanation:

"The amount of rain that fell over two days" means the sum of the two amounts of rain that fell on Saturday and Sunday.

`1(1)/(16) +0.4=1(10)/(160) + (4)/(10) = 1(10)/(160) + (64)/(160) = 1(74)/(160)`

This number is close to
`1(80)/(160)`, which is 1.5 inches.

Answer 2

0.5 Inches

Explanation:

1/16=.0625 which is about .1 for estimating purposes

.1 on Saturday + .4 on Sunday = .5 inches of rain over the two days
