Question

The distance between two towns is 80 3/4

kilometers. There is approximately 1.6
kilometers in 1 mile.
What is the number of miles between these two towns? Round to the hundredths place.

Answer 1

Explanation:

`(80)/(1) + (3)/(4) \\ (80 * 4 + 3 * 1)/(4) \\ (320 + 3)/(4) = (323)/(4) \\ (323)/(4) * (16)/(10) \\ = (5168)/(40) = 5168 / 40 = 129.2`

First of all... convert every number in fraction n/1 and then find how many kilometres are between (+). Then you multiply by 1.6 (16/10 in fraction) to find how many miles are there. And then (optional) I converted back to whole number. There are 129.2 miles between the towns.
