Visual Learning Bridge
The Chisholm Trail was used to drive cattle to market. Ross’s herd has walked \(\frac{1}{2}\) the distance to market. What is another way to name \(\frac{1}{2}\)?

\(\frac{1}{2}\) = \(\frac{}{}\) You can use fraction strips.

The fractions \(\frac{1}{2}\) and \(\frac{2}{4}\) represent the same part of the whole.
Two \(\frac{1}{4}\) strips are equal to \(\frac{1}{2}\), so \(\frac{1}{2}\) = \(\frac{2}{4}\).
Another name for \(\frac{1}{2}\) is \(\frac{2}{4}\).

You can find other equivalent fractions. Think about fractions that name the same part of the whole.

Four \(\frac{1}{8}\) strips are equal to \(\frac{1}{2}\), so \(\frac{1}{2}\) = \(\frac{4}{8}\).
Another name for \(\frac{1}{2}\) is \(\frac{4}{8}\)

Convince Me! Look for Relationships In the examples above, what pattern do you see in the fractions that are equivalent to \(\frac{1}{2}\)? What is another name for \(\frac{1}{2}\) that is not shown above?

Topic 13 Performance Task

Clothing Store Devin, Jenna, Eli, and Gabby work at a clothing store. On Saturday they each worked the same number of hours.

The Time Spent at Cash Register table shows the fraction of time each person spent checking out customers. The Time Spent on Customer Calls table shows the fraction of an hour Jenna spent answering phone calls for the store.

Use the Time Spent at Cash Register table to answer Questions 1-3.

Question 1.
Draw fraction strips to show the fraction of time each person worked at the cash register.

Answer:
The fraction of time each person worked at the cash register = 3/6, 2/6, 6/6, and 5/6.

Explanation:
In the above-given question,
given that,
Devin, Jenna, Eli, and Gabby work at a clothing store.
Devin worked 3/6 hours a day.
Jenna worked 2/6 hours a day.
Eli worked 6/6 hours a day.
Gabby worked 5/6 hours a day.
the fraction of hours is 3/6, 2/6, 6/6, and 5/6.
so the fraction of time each person worked at the cash register = 3/6, 2/6, 6/6, and 5/6.

Question 2.
Who spent the most time at the cash register?

Answer:
The most time spent at the cash register = Gabby.

Explanation:
In the above-given question,
given that,
Devin, Jenna, Eli, and Gabby work at a clothing store.
Devin worked 3/6 hours a day.
Jenna worked 2/6 hours a day.
Eli worked 6/6 hours a day.
Gabby worked 5/6 hours a day.
3/6 = 1/2.
3 x 1 = 3.
3 x 2 = 6.
2/6 = 1/3.
2 x 1 = 2.
2 x 3 = 6.
6 / 6 = 1.
so the number of hours Gabby worked = 5/6.

Question 3.
Write a comparison to show the time Gabby spent at the cash register compared to the time Devin spent. Use >, <, or =.

Answer:
Gabby worked more hours than Devin.

Explanation:
In the above-given question,
given that,
Devin, Jenna, Eli, and Gabby work at a clothing store.
Devin worked 3/6 hours a day.
Jenna worked 2/6 hours a day.
Eli worked 6/6 hours a day.
Gabby worked 5/6 hours a day.
5/6 is greater than 3/6.
so Gabby worked more hours than Devin.

Question 4.
Use the Time Spent on Customer Calls table to answer this question: On which day did Jenna spend closest to one hour on the phone? Explain how you know.

Answer:
Jenna spends the closest to one hour on Monday.

Explanation:
In the above-given question,
given that,
on Saturday he spends a 3/6 fraction of an hour.
on Sunday he spends 3/5 fraction of an hour.
on Monday he spends 3/4 fraction of an hour.
3/6 = 1/2.
3/4 is nearest to the 1.
so Jenna spends the closest to one hour on Monday.
