![### Unit 4 Review: Ratios & Rates
Complete the problems below to assess how much you have learned about ratios and rates. Refer to your notes as needed. Each part is worth 1 point.
#### 1. Write each rate as a fraction. Then simplify the fraction to the lowest terms. Be sure to include the appropriate words/units for each scenario. The first one is started for you.
a) **5 flight attendants for 150 passengers:**
\[
\frac{5 \text{ flight attendants}}{150 \text{ passengers}} = \frac{1}{30}
\]
b) **Samantha rode her bike 6 miles in 48 minutes:**
\[
\frac{6 \text{ miles}}{48 \text{ minutes}} = \frac{1}{8}
\]
#### 2. A poll at Ford College’s branch campus found that about 800 out of 1200 students are unmarried.
a) **Ratio of married to unmarried students:**
\[
\frac{400 \text{ married students}}{800 \text{ unmarried students}} = \frac{1}{2}
\]
b) **Ratio of married students to the total number of students as a simplified fraction:**
\[
\frac{400 \text{ married students}}{1200 \text{ total students}} = \frac{1}{3}
\]
#### 3. Jay had a party. Including Jay, there were a total of 25 people. 10 of them live in Reading.
a) **Which is greater: The ratio of people at the party living in Reading to people not living in Reading or the ratio of those living in Reading to the total number of people at the party?**
\[
\text{Ratio of people in Reading to not in Reading:} \frac{10}{15} = \frac{2}{3}
\]
\[
\text{Ratio of people in Reading to total people:} \frac{10}{25} = \frac{2}{5}
\]
The ratio of people at the party living in Reading to people not living in Reading is greater.
b) **Justify your answer.**
The fraction \(\frac{2}{3}\) is](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F75f8d7f9-7f0c-41f6-8f47-d888039b56f4%2F3dc72644-2b8d-44d1-8ebb-0be84b0f931c%2Fybgejaj_processed.jpeg&w=3840&q=75)
