Ihave a math teacher that doesnt really do a good job teaching math and i need to know how to change ratios to unit rates

Examples of How to Find Unit Rate or Unit Price

Ryan purchased 3 apples for $1.80. What is the unit price, or the cost of one apple?

We want to know the price per apple unit so we set up a ratio with the number of apples in the denominator. The total price goes in the numerator. So the fraction is 1.80/3.Complete the division: 1.80 ÷ 3 = .60. You can conclude that the per apple price unit rate is $0.60/1. Ryan paid a unit price of $0.60 per apple (60 cents per 1 apple = .60/1).

The pottery store can make 176 coffee mugs in an 8 hour day. How many mugs can they make in one hour?

We want to know the number of mugs made per hour unit so we set up a ratio with hours in the denominator. The total number of mugs made per day goes in the numerator. So the fraction is 176/8.Complete the division: 176 ÷ 8 = 22. You can conclude that the per hour mug-making unit rate is 22/1. The pottery store makes 22 mugs per hour (22 mugs per 1 hour = 22/1).

Kylie can run 12 laps in 30 minutes. How many laps does she run per minute?

We want to know the laps per minute unit so we set up a ratio with minutes in the denominator. The total laps goes in the numerator. So the fraction is 12/30.Complete the division: 12 ÷ 30 = 0.4. You can conclude that the per minute lap unit rate is 0.4/1. Kylie can run 0.4 laps per minute (0.4 laps per 1 minute = 0.4/1).

Iam guessing c. or d.
