Finding Fractional Unit Rates Using a Graph

This video tutorial teaches how to find unit rates using graphs, focusing on fractional unit rates. It explains the process of identifying unit rates from graphs, even when the result is not an integer, and emphasizes the efficiency of using fractions over decimals. The tutorial provides examples of finding unit rates from graphs, including cases with non-integer coordinates and missing scale numbers. It concludes with advanced examples, demonstrating how to calculate unit rates in different scenarios.

What is a common mistake when calculating unit rates with non-integer results?

• Using fractions

• Ignoring the graph

• Always converting to decimals

• Multiplying instead of dividing

How can you find the unit rate if the graph does not show integer values directly?

• By converting all values to decimals

• By using ordered pairs from the graph

• By using a calculator

• By guessing the values

What does the ordered pair (5, 3) represent in the context of unit rates?

• 3 miles in 5 minutes

• 3 dollars for 5 pounds

• 5 miles in 3 minutes

• 5 dollars for 3 pounds

When scales are not labeled, what method can be used to find the unit rate?

• Using two ordered pairs with integer coordinates

• Using a single ordered pair

• Ignoring the graph

• Estimating the values

If 4 additional pounds cost 5 additional dollars, what is the unit rate in dollars per pound?

• $1.25 per pound

• $1.50 per pound

• $2.00 per pound

• $0.80 per pound
