Eureka Math Grade 3 Module 3 Lesson 3 Problem Set Answer Key

Question 1.
Each equation contains a letter representing the unknown. Find the value of the unknowns, and then write the letters that match the answers to solve the riddle.

Answer:
e = 20, i = 1/ 6, s = 4, n = 10, k = 6, a = 2.6, l = 7, c = 3, t = 0.7, b = 2, h = 5.

Explanation:
In the above-given question,
given that,
The equation contains the letter representing unknown.
5 x 4 = e , e = 20.
24/ i = 4, i = 4/ 24 = 1/6.
32 = s x 8, s = 32/ 8, s = 4.
8 = 80 / n, n = 10.
8 = a / 3, a = 2.6.
21 / 3 = l, l = 7.
21 = c x 7, c = 3.
t / 10 = 7, t = 0.7.
24/b = 12, b = 24/ 12, b = 2.
35 = 7 x h, h = 5.

Which tables do you NOT have to learn?

Answer:
The tables not have to learn is 10, 20, and 70.

Explanation:
In the above-given question,
given that,
The tables are 9, 6, 3, 5, 70, 20, 10, 24, 2, 7, and 4.
out of all the tables 10 and 20 are very easy.
so we need not to learn.

Question 2.
Lonna buys 3 t-shirts for $8 each.
a. What is the total amount Lonna spends on 3 t-shirts? Use the letter m to represent the total amount of money Lonna spends, and then solve the problem.

Answer:
The total amount of money Lonna spends = 24$.

Explanation:
In the above-given question,
given that,
Lonna buys 3 t-shirts for $8 each.
m x 3 = $8.
m = 8 x 3.
m = $24.
so the total amount of money Lonna spends = $24.

b. If Lonna hands the cashier 3 ten dollar bills, how much change will she receive? Use the letter c in an equation to represent the change, and then find the value of c.

Answer:
The change she received = $6.

Explanation:
In the above-given question,
given that,
Lonna hands the cashier 3 ten dollar bills.
c x 30 = 24.
c = 30 – 24.
c = $6.
so the change Lonna received = $6.

Question 3.
Miss Potts used a total of 28 cups of flour to bake some bread. She used 4 cups of flour for each loaf of bread. How many loaves of bread did she bake? Represent the problem using multiplication and division sentences and a letter for the unknown. Then, solve the problem.
__7___ × ___4__ = __28____
__28___ ÷ __4___ = ___7___

Answer:
The number of loaves of bread did she bake = 7.

Explanation:
In the above-given question,
given that,
Miss potts used a total of 28 cups of flour to bake some bread.
she used 4 cups of flour for each loaf of bread.
7 x 4 = 28.
28 / 4 = 7.
so the number of loaves of bread did she bake = 7.

Question 4.
At a table tennis tournament, two games went on for a total of 32 minutes. One game took 12 minutes longer than the other. How long did it take to complete each game? Use letters to represent the unknowns. Solve the problem.

Answer:
The other game takes to complete = 10 minutes.

Explanation:
In the above-given question,
given that,
At a table tennis tournament, two games went on for a total of 32 minutes.
one game took 12 minutes longer than the other.
32 + t = 12.
t = 32 – 12.
t = 20.
so the other game takes to complete = 10 minutes.
