Question

Round 3..............almost out of points .-.

Answer 1

You can use a proportion.

2/3 inch is to 1 hour as 6 2/3 inch is to x hours.


`((2)/(3)~inch)/(1~hour) = (6 (2)/(3)~inch)/(x)`

Cross multiply to get


`(2)/(3) x = 6 (2)/(3)`


`(2)/(3) x = (20)/(3)`


`2x = 20`


`x = 10`

Answer: It rained for 10 hours.

Answer 2

6 2/3 ÷ 2/3
= 20/3 ÷ 2/3
= 20/3 × 3/2
= 20/2
= 10

Answer
10 hours
