One simple question: how much for one?
A unit rate compares a quantity with exactly one unit of another quantity. The unit matters just as much as the number.
Make the second quantity one
12 ÷ 4 = 3. So one pencil costs 3 dollars.
State the unit rate
The unit rate is $3 per pencil, not simply “3.”
Try a second example
Traveling at a constant speed
A bicyclist travels 30 miles in 5 hours. To find miles per hour, divide 30 ÷ 5 = 6. The unit rate is 6 miles per hour. This works because the speed remains constant.
