The video tutorial explains how to calculate unit rates involving complex fractions. Cassandra conducts an experiment to measure rainfall over half an hour, resulting in a complex fraction. The tutorial details the process of converting this complex fraction into a unit rate, predicting the rainfall for one hour. Key concepts include understanding complex fractions, calculating unit rates, and applying these calculations to real-world scenarios.

What is a unit rate?

• A rate with a denominator of 2

• A rate with both numerator and denominator as fractions

• A rate with a numerator of 1

• A rate with a denominator of 1

What did Cassandra use to measure the rainfall?

• A rain gauge

• An empty cup

• A measuring tape

• A ruler

How much rain did Cassandra measure in the cup after half an hour?

• Nine eighths of an inch

• One and a half inches

• One inch

• Two inches

What is the purpose of Cassandra's experiment?

• To test the accuracy of her predictions

• To find the rate of rainfall per hour

• To measure the total rainfall for the day

• To compare different measurement tools

What is a complex fraction?

• A fraction with a negative number

• A fraction with a decimal

• A fraction with a fraction in its numerator or denominator

• A fraction with a whole number

Why did Cassandra want to find the rate of rainfall for one hour?

• To find an equivalent fraction with a denominator of one hour

• To predict the total rainfall for the day

• To check the accuracy of her measurement

• To compare with other weather reports

What does the denominator represent in a unit rate?

• The numerator's value

• The total amount

• The unit of measurement

• The time period or quantity of one

What is the first step in calculating a unit rate from a complex fraction?

• Multiply the numerator by the denominator

• Add the numerator and denominator

• Divide the numerator by the denominator

• Subtract the denominator from the numerator

How do you change a division expression to a multiplication one when dealing with fractions?

• By dividing the fractions

• By subtracting the fractions

• By flipping the second fraction and multiplying

• By adding the fractions

What mathematical operation is used to simplify the division of fractions?

• Addition

• Subtraction

• Multiplication

• Division
