A unit rate is the amount for just one. Find it by dividing. Once you know the rate for one, multiply to scale up to any amount.
Your quick check picks one for you, but you can switch any time:
Level 0 Divide to find the cost of one.
A. 6 stickers cost $6. One sticker costs $6 ÷ 6 = $___?
6 ÷ 6 = 1.
B. 8 apples cost $8. One apple costs $8 ÷ 8 = $___?
8 ÷ 8 = 1.
C. 10 pens cost $20. One pen costs $20 ÷ 10 = $___?

Level 1 Find the rate, then use it.
A. 3 books cost $9. One book costs $9 ÷ 3 = $___?
9 ÷ 3 = 3.
B. So 5 books cost 5 × $3 = $___?
5 × 3 = 15.
Level 2 Solve a full rate problem.
A. A car goes 100 miles on 4 gallons. How many miles per 1 gallon?
100 ÷ 4 = 25 miles per gallon.
