Question

PLEASE HELP

What should the following rate be divided by to convert it to a unit rate?
16 inches/12 hours

Answers:

A) 6/6

B) 2/2

C) 12

D) 12/12

Answer 1

12/12

Explanation:

I would say simply perform the division already indicated.

(16 in)/(12 h) = 16/12 in/h = 4/3 in/h

Alternatively, divide the given rate by 1. The form 12/12 gives you the same thing as above:

(16 in)/(12 h)/(12/12) = (16/12) in/h = 4/3 in/h
