which fraction is a unit rate you can use to solve a ratio problem

A unit rate is a rate that is simplified to a denominator of 1.

To solve a ratio problem, you can use a fraction that represents the relationship between two quantities.

Example: Let's say you have a ratio problem that states "Sarah read 30 pages in 2 hours. How many pages does she read in 1 hour?"

To solve this problem, you can set up a fraction as a unit rate:

Pages read (numerator) / Time (denominator)

In this case, Sarah read 30 pages in 2 hours, so the fraction would be:

30 pages / 2 hours

Simplifying this fraction would give you a unit rate:

15 pages / 1 hour

This means Sarah reads 15 pages in 1 hour.
