Answer:
Liz’s go-kart has more fuel.

Explanation:
The fuel tank in Liz’s go-kart = \(\frac{3}{5}\) full.
The fuel tank in Alvin’s go-kart = \(\frac{1}{3}\) full.
\(\frac{3}{5}\) full = 1\(\frac{3}{5}\) = (5 + 3) ÷ 5
= \(\frac{8}{5}\) = 1.6.
\(\frac{1}{3}\) full = 1\(\frac{1}{3}\) = (3 + 1) ÷ 3
= \(\frac{4}{3}\) = 1.33.

Turn and Talk Why is it important that the size of the fuel tanks in the go-karts is the same?
Answer:
It is important that the size of the fuel tanks in the go-karts is the same because the maximum size of a fuel tank is limited by the weight allowed and the space available on a vehicle.

Explanation:
The maximum size of a fuel tank is limited by the weight allowed and the space available on a vehicle.

A. How does your fraction model represent \(\frac{4}{5}\) mile?
____________________________________

B. How does your fraction model represent \(\frac{7}{8}\) mile?
____________________________________

C. How can you use your fraction models to compare the lengths of the tracks?

D. Which track is shorter?
Answer:
Track A is shorter.

Explanation:
Length of track A = \(\frac{4}{5}\) mile = 0.8 mile.
Length of track B = \(\frac{7}{8}\) mile = 0.875 mile.

Turn and Talk The fractions \(\frac{4}{5}\) and \(\frac{7}{8}\) each have one piece missing from the whole. How can you use the sizes of the missing pieces to compare the two fractions?
Answer:
\(\frac{1}{5}\)  > \(\frac{1}{8}\) because numerators are same, denominators are consider. lesser number becomes greater than the bigger number.

Explanation:
fractions \(\frac{4}{5}\) and \(\frac{7}{8}\)
Missing pieces:
\(\frac{4}{5}\) + ?? = 1
=> ?? = 1 – \(\frac{4}{5}\)
=> ?? = (5 -4) ÷ 5
=> ?? = \(\frac{1}{5}\)
\(\frac{7}{8}\) + ?? = 1
=> ?? = 1 – \(\frac{7}{8}\)
=> ?? = (8 – 7) ÷ 8
=> ?? = \(\frac{1}{8}\)

 

2. It takes Jack \(\frac{3}{4}\) hour to fix a tire. It takes Renee \(\frac{2}{3}\) hour to fix a tire. Who takes a longer time to fix a tire?
A. Complete the visual model to show the time for each person.

C. Use the symbols < or > to write a statement comparing the two fractions.
\(\frac{3}{4}\) HMH Into Math Grade 4 Module 11 Lesson 1 Answer Key Compare Fractions Using Visual Models 6 \(\frac{2}{3}\)
Answer:
Renee takes a longer time.
\(\frac{3}{4}\) > \(\frac{2}{3}\)

Explanation:
Number of hours Jack takes to a tire =  \(\frac{3}{4}\) = 0.75.
Number of hours Renee takes to a tire = \(\frac{2}{3}\) = 0.67.

Question 1.
Emma fills \(\frac{3}{5}\) of a jug with water. She fills \(\frac{4}{6}\) of a same-sized jug with sports drink. Does Emma pour more water or more sports drink?

Complete the visual models to solve. Justify your answer.
Answer:
Emma pours more sports drink than water.
HMH-Into-Math-Grade-4-Module-11-Lesson-1-Answer-Key-Compare-Fractions-Using-Visual-Models-Check Understanding Math Board-1

Explanation:
Amount of water Emma fills in a jug = \(\frac{3}{5}\)
Amount of sports drink Emma fills in a jug = \(\frac{4}{6}\)
\(\frac{4}{6}\) = \(\frac{4}{6}\) ÷ \(\frac{2}{2}\) = \(\frac{2}{3}\)
\(\frac{3}{5}\) = 0.6
\(\frac{4}{6}\) = 0.67.
\(\frac{3}{5}\) < \(\frac{4}{6}\)

 

Complete the visual model to show each fraction. Then write < or > to compare.

  • Who eats less of his granola bar? _____

Answer:
Marc eats less of his granola bar.
HMH-Into-Math-Grade-4-Module-11-Lesson-1-Answer-Key-Compare-Fractions-Using-Visual-Models-On Your Own-4

Explanation:
Amount of a granola bar Marc eats = \(\frac{5}{8}\)
Amount of a granola bar Harold eats = \(\frac{4}{6}\)
\(\frac{4}{6}\) = \(\frac{4}{6}\) ÷ \(\frac{2}{2}\) = \(\frac{2}{3}\)
\(\frac{5}{8}\) = 0.625.
\(\frac{4}{6}\) = 0.67
\(\frac{5}{8}\) < \(\frac{4}{6}\)

Answer:
Length of the wall Kelly paints = \(\frac{1}{2}\) – x => 0 to 0.49.
HMH-Into-Math-Grade-4-Module-11-Lesson-1-Answer-Key-Compare-Fractions-Using-Visual-Models-Reason-5

Explanation:
Length of the wall Quinn paints = \(\frac{1}{2}\) = 0.5.
Length of the wall Kelly paints be x.
=> Length of the wall Kelly paints = \(\frac{1}{2}\) – x.
=> 0 to 0.49.

I’m in a Learning Mindset
Which strategy did you prefer for comparing fractions—using visual models or using concrete models? Why?
_______________________________________
Answer:
I would prefer for visual models for comparing fractions because they are easier to understand and to solve the problem in no time than concrete models.
