Explain how the Commutative and Associative Properties of Addition are alike and how they are different.
Answer:
The Commutative and Associative Properties of Addition are alike:
Both commutative and associative properties are rules applied to addition and multiplication operations.
These properties are laws used in algebra to help solve problems.
The difference between Commutative and Associative Properties of Addition are:
The commutative property comes from the term “commute” which means ‘move around’ and it refers to being able to switch numbers that you’re adding or multiplying regardless of the order of the numbers.
The associative property, on the other hand, comes from the word “associate” or “group” and it refers to grouping of three or more numbers using parentheses, regardless of how you group them. The result will be the same, no matter how you re-group the numbers or variables.

Question 4.

Cole brought a submarine sandwich to the picnic. He shared the sandwich equally with 3 friends. The sandwich was cut into eighths. What are two ways to describe the part of the sandwich each friend ate?

• How many people shared the sandwich?
Answer:
It is given that
Cole brought a submarine sandwich to the picnic. He shared the sandwich equally with 3 friends. The sandwich was cut into eighths
Hence, from the above,
We can conclude that
The number of people that shared the sandwich is: 3 people

Cole grouped the smaller pieces into twos. Draw circles to show equal groups of two pieces to show what each friend ate.

There are 4 equal groups. Each group is \(\frac{1}{4}\) of the whole sandwich. So, each friend ate \(\frac{1}{4}\) of the whole sandwich.
How many eighths did each friend eat?
Answer:
The number of eighths did each friend eat is: 2 eighths

\(\frac{1}{4}\) and \(\frac{2}{8}\) are equivalent fractions since they both name the same amount of the sandwich.
So,
\(\frac{1}{4}\) and \(\frac{2}{8}\) of the sandwich are two ways to describe the part of the sandwich each friend ate.

Example Model the problem.
Heidi ate \(\frac{3}{6}\) of her fruit bar. Molly ate \(\frac{4}{8}\) of her fruit bar, which is the same size. Which girl ate more of her fruit bar?
Shade \(\frac{3}{6}\) of Heidi’s fruit bar and \(\frac{4}{8}\) of Molly’s fruit bar.


• Is \(\frac{3}{6}\) greater than, less than, or equal to \(\frac{4}{8}\)?
Answer:
The given fractions are:
\(\frac{3}{6}\) and \(\frac{4}{8}\)
So,
\(\frac{3}{6}\) = \(\frac{4}{8}\) = \(\frac{1}{2}\)
Hence, from the above,
We can conclude that
\(\frac{3}{6}\) is equal to \(\frac{4}{8}\)
So,
Both girls ate the same amount.

Texas Go Math Grade 3 Lesson 3.3 Answer Key Compare Fractions

Essential Question
What strategies can you use to compare fractions?
Answer:
Equivalence can be used to make fractions easier to compare. For instance, to use the common denominator strategy to compare \(\frac{2}{5}\) and \(\frac{3}{8}\), each fraction can be rewritten as an equivalent fraction with a denominator of 40. Once the denominators are the same, one can simply compare the size of the resulting numerators

Example 1
Molly and Omar are decorating the same-size bookmarks. Molly covers \(\frac{2}{3}\) other bookmark with glitter. Omar covers \(\frac{1}{3}\) of his bookmark with glitter. Whose bookmark is covered with more glitter?

• Do you need to look at the numerators or the denominators?
Answer:
It is given that
Molly and Omar are decorating the same-size bookmarks. Molly covers \(\frac{2}{3}\) other bookmark with glitter. Omar covers \(\frac{1}{3}\) of his bookmark with glitter
Now,
The given fractions are:
\(\frac{2}{3}\) and \(\frac{1}{3}\)
Hence, from the above,
We can conclude that
We need to look at the numerators since the denominators are the same

Use reasoning to compare \(\frac{2}{3}\) and \(\frac{1}{3}\).

• Both fractions involve third-size pieces. 2 pieces are more than 1 piece.
• 
  So, Molly’s bookmark is covered with more glitter.

Same Denominator Strategy

• When the denominators are the same, you can compare only the number of pieces, or the numerators.

Example 2
Ms. Davis is making a fruit salad with \(\frac{3}{4}\) pound of cherries and \(\frac{3}{8}\) pound of strawberries. Which weighs less, the cherries or the strawberries?

Use reasoning to compare \(\frac{3}{4}\) and \(\frac{3}{8}\).
• \(\frac{1}{8}\) is less than \(\frac{1}{4}\) because there are more pieces.

Same Numerator Strategy
• When the numerators are the same, look at the denominators to compare the size of the pieces.
So,
The strawberries weigh less.

Mia’s baseball bat is 32 inches long. What is its length rounded to the nearest ten inches?
Answer:
30 inches
Explanation:
To round a two-digit number to the nearest ten,
simply increase it or decrease it to the nearest number that ends in 0.
When a number ends in 1, 2, 3, or 4, bring it down;
in other words, keep the tens digit the same and turn the ones digit into a 0.

Remember
When you round a number you find a number that tells you about how much or about how many.
Answer:
When rounding a number you will “round up” or “round down”.
When the number you are rounding is between 0-4, you round down to the next lowest number.
When the number is 5-9, you round the number up to the next highest number.
When we round a number, we round it to the nearest place value.

One Way Use place value to round.

A. Round 32 to the nearest ten.
Think: The digit in the ones place tells if the number is closer to 30 or 40.

2 < 5
So, the tens digit stays the same. Write 3 as the tens digit.
Write zero as the ones digit.
So, the length of Mias bat rounded to the nearest ten inches is ________ inches.
Answer:
30 inches
Explanation:
Mia’s baseball bat is 32 inches long, which is given in the above question.
When we round the length of Mias bat to the nearest ten inches it becomes 30 inches.

B. Round 457 to the nearest hundred.

Think: The digit in the tens place tells if the number is closer to 400 or 500.

5 = 5
So, the hundreds digit increases by one.
Write 5 as the hundreds digit.
Write zeros as the tens and ones digits.
So, 457 rounded to the nearest hundred is ________.
Answer: 500
Explanation:
To round a number to the nearest 100, look at the tens digit at first.
 If the tens digit is 5 or more, round up.
If the tens digit is 4 or less, round down.

Another Way Use a number line to round.

Locate and label 718 on the number lines.

A. Round 718 to the nearest ten.

718 is closer to ________ than it is to ________.
