Eureka Math Grade 6 Module 2 Lesson 1 Example Answer Key

Example 1:
\(\frac{1}{2} \div \frac{1}{8}\)
Answer:
Step 1: Decide on an interpretation.
For today, we will only use the measurement interpretation and consider the divisor, 1 eighth, to be the size of the group.

Step 2: Draw a model

Eureka Math Grade 6 Module 2 Lesson 5 Example Answer Key 4

Step 3: Find the answer.
\(\frac{1}{2} \div \frac{1}{8}=\frac{4}{8} \div \frac{1}{8}\) = 4 eighths ÷ 1 eighth = 4
So, the answer is 4. There are four \(\frac{1}{8}\) in \(\frac{1}{2}\).

Step 4: Choose a unit.
Answers will vary, but pounds will be used throughout the discussion below.

Step 5: Set up a situation based upon the model.
Answers will vary, but there is a story problem provided in the discussion.

Example 2.
\(\frac{3}{4} \div \frac{1}{2}\)
Answer:
Step 1: Decide on an interpretation.
For today, we’ll only use the measurement interpretation and consider the divisor, 1 half, to be the size of the group.

Step 2: Draw a diagram.
Eureka Math Grade 6 Module 2 Lesson 5 Example Answer Key 5

Step 3: Find the answer.
\(\frac{3}{4} \div \frac{1}{2}=\frac{3}{4} \div \frac{2}{4}\) = 3 fourths ÷ 2 fourths = \(\frac{3}{2}\) = 1\(\frac{1}{2}\)
So, the answer is \(\frac{1}{2}\). There are 1\(\frac{1}{2}\) halves in \(\frac{3}{4}\).

Step 4: Choose a unit.
Answers will vary, but ounces will be used throughout the discussion below.

Step 5: Set up a situation based on the model.
Answers will vary, but there is a story problem provided in the discussion.

Question 10.
Parks spent \(\frac{1}{3}\) of his money on a sweater. He spent \(\frac{3}{5}\) of the remainder on a pair of jeans. If he has $36 left, how much did the sweater cost?
Answer:
\(\frac{2}{5} \text { of } \frac{2}{3}=\frac{6}{15}\)
\(\frac{1}{3}+\frac{6}{15}=\frac{11}{15}\)
\(\frac{4}{15}\) of Parks’s money is left over.

$36 is \(\frac{4}{15}\) of what number?
4 units = 36
1 unit = 36 ÷ 4 = 9
5 units = 5 × 9 = 45
The sweater cost $45.
