Question

A unit rate is

• A. a ratio between two different units with a numerator of 1
• B. a ratio between two same units with a denominator of 1
• C. a ratio between two same units with a numerator of 1
• D. a ratio between two different units with a denominator of 1

Answer 1

The correct option is D a ratio between two different units with a denominator of 1

A unit rate means a rate for one of something. We write this as a ratio with a denominator of one.

For example, if you ran 80 meters in 10 seconds, on average you ran 8 meters in 1 second. Here, the ratio 8 meters in 1 second is a unit rate.

Also units of both the quantities are different i.e. meter and second.
