I need help with this. I have been stuck on it for a while. I'm not asking for answers, just a small explanation on how would I be able to find the answer.

Question

Convert the map scale to a unit rate. How many inches represent one mile?

3/10in.=7/8mi.

Thank you.

Answer 1

you want to end up with a unit rate of in/mi. So, divide the inches by the miles:

(3/10 in) / (7/8 mi) = (3/10)/(7/8) in/mi = 3/10 * 8/7 in/mi = _____ in/mi

Answer 2

Multiply both sides by 8/7.
