Unit Rates

The video tutorial explains how Rachel determines the number of pages she can read in 45 minutes by calculating her reading rate. It introduces the concept of rates and unit rates, showing how to convert a rate to a unit rate by dividing the numerator by the denominator. The tutorial then applies this unit rate to find out how many pages Rachel can read in a given time, concluding with a summary of the lesson on using unit rates to solve word problems.

What is the rate at which Rachel reads?

• 45 pages in 54 minutes

• 12 pages in 10 minutes

• 10 pages in 12 minutes

• 1 page in 1 minute

What is a unit rate?

• A rate with a denominator of 10

• A rate with equal numerator and denominator

• A rate with a numerator of 1

• A rate with a denominator of 1

How do you calculate a unit rate from a given rate?

• Add the numerator and denominator

• Subtract the denominator from the numerator

• Divide the numerator by the denominator

• Multiply the numerator by the denominator

If Rachel reads 1.2 pages in 1 minute, how many pages can she read in 45 minutes?

• 50 pages

• 60 pages

• 54 pages

• 45 pages
