2.1 Classifying Rational Numbers

Question 1.
Five friends divide three bags of apples equally between them.
Write the division represented in this situation as a fraction.
Answer:
As 5 friends divide 3 bags of apples equally between them, we can write it as fraction as:
\(\frac{3}{5}\)

Write each rational number as \(\frac{a}{b}\)

Question 2.
5\(\frac{1}{6}\) __________________
Answer:
Firstly, we will write the whole number as a sum of ones
Secondly, we will use the denominator to find corresponding fractions for ones.
Thirdly, we will calculate sum of numerators!
To reach our final solution: improper fraction.
5\(\frac{1}{6}\) = 1 + 1 + 1 + 1 + 1 + \(\frac{1}{6}\)
= \(\frac{6}{6}+\frac{6}{6}+\frac{6}{6}+\frac{6}{6}+\frac{6}{6}+\frac{1}{6}\)
= \(\frac{31}{6}\)

Question 7.
Find the opposite of \(\frac{1}{3}\) and – \(\frac{7}{12}\) __________
Answer:
As i mentioned before, opposite of any number is number with added – sign on left side!
Opposite of \(\frac{1}{3}\) is –\(\frac{1}{3}\)
Opposite of – \(\frac{7}{12}\) is \(\frac{7}{12}\)
– \(\frac{1}{3}\) and \(\frac{7}{12}\)

Go Math Grade 6 Module 2 Answer Key Pdf Question 8.
Find the absolute value of 9.8 and –\(\frac{7}{8}\) __________
Answer:
Absolute value of some number is its distance from 0 on the number line!
|9.8| = 9.8
|- \(\frac{10}{3}\)| = \(\frac{10}{3}\)
9.8 and \(\frac{10}{3}\)

2.3 Comparing and Ordering Rational Numbers

Question 9.
Over the last week, the daily low temperatures in degrees Fahrenheit have been – 4, 6.2, 18\(\frac{1}{2}\), – 5.9, 21, – \(\frac{1}{4}\), and 1.75. List these numbers in order from greatest to least.
Answer:
First thing will be writing fractions as equivalent decimals!
18\(\frac{1}{2}\) = 18 + \(\frac{1}{2}\) = 18 + 0.5 = 18.5
– \(\frac{1}{4}\) = – 0.25

Now we know that number 21 is greater than 18.5 which is greater than 6.2 which is greater than 1.75 which is
greater than – 0.25 which ¡s greater than – 4 which is greater than – 5.9.
One last thing to do is to return decimals to given expressions and write it in order from greatest to least!
21, 18\(\frac{1}{2}\), 6.2, 1.75, –\(\frac{1}{2}\), – 4, – 5.9

Division:
\(\frac{1}{2}\) is very easy, so we won’t show it!
Texas Go Math Grade 6 Module 2 Quiz Answer Key 9

Essential Question

Question 10.
How can you solve problems by ordering rational numbers from least to greatest?
Answer:
Firstly, we have to convert all expressions into same, as shown in examples above, we can work with fractions or
decimals, depending on given terms!
Secondly, we compare our decimals/fractions and order them from least to greatest!
Note that we compare numerators when dealing with fractions. That works because we get them to have same denominator!
One last thing to do is to return them in given format and write a final solution!

Selected Response

Question 1.
Suki split five dog treats equally among her six dogs. Which fraction represents this division?
(A) \(\frac{6}{5}\) of a treat
(B) \(\frac{5}{6}\) of a treat
(C) \(\frac{1}{5}\) of a treat
(D) \(\frac{1}{6}\) of a treat
Answer:
As Suki splits 5 dog treats among 6 dogs.
Each dog will get
\(\frac{5}{6}\) treats

(B) \(\frac{5}{6}\) of a treat

Question 2.
Which set or sets does the number 15 belong to?
(A) whole numbers only
(B) rational numbers only
(C) integers and rational numbers only
(D) whole numbers, integers, and rational
Answer:
The number 15 belongs to a set of Whole numbers and therefore to a set of Integers and Rational numbers.
We can say that because we know that a set of Whole numbers is included in the set of Integers, and a set of Integers is included in the set of Rational numbers.

Integers Quiz Grade 6 Module 2 Test Answers Math Question 3.
Which of the following statements about rational numbers is correct?
(A) All rational numbers are also whole numbers.
(B) All rational numbers are also integers.
(C) All rational numbers can be written in the form \(\frac{a}{b}\).
(D) Rational numbers cannot be negative.
Answer:
Statement that all rational numbers are also whole numbers is surely incorrect!
For example, 0.5 is a decimal, which is not whole number!

Statement that all rational numbers are also integers is also incorrect!
We can use same example from last statement to prove it.

Statement that all rational numbers can be written in form of \(\frac{a}{b}\) is correct!
Really, it is…take a look at some examples that prove our theory:
0.5 = \(\frac{1}{2}\)
– 5 = \(\frac{-5}{1}\)
5 = \(\frac{5}{1}\)

Statement that rational numbers cannot be negative is incorrect!
We can simply take a look on Venn’s diagram(which we worked in previous lecture) to convince ourselves that this is false statement!

(C) All rational numbers can be written in the form \(\frac{a}{b}\).

Question 4.
Which of the following shows the numbers in order from least to greatest?
(A) –\(\frac{1}{5}\), – \(\frac{2}{3}\), 2, 0.4
(B) 2, –\(\frac{2}{3}\), 0.4, – \(\frac{1}{5}\)
(C) – \(\frac{2}{3}\), 0.4, – \(\frac{1}{5}\), 2
(D) – \(\frac{2}{3}\), – \(\frac{1}{5}\), 0.4, 2
Answer:
Let’s transform all the given numbers into fractions first and make them have 15 as common denominator
Texas Go Math Grade 6 Module 2 Quiz Answer Key 10

Now, we compare their numerators to find out their order
30, 6, – 3, – 10
Number – 10 is less than – 3 which is less than 6 which is Less than 30.
So, now we know order of numerators, and therefore we know order of whole fractions

So, numbers in order from least to greatest are:
\(-\frac{10}{15},-\frac{3}{15}, \frac{6}{15}, \frac{30}{15}\)
Now, we can return them in given form and get:
– \(\frac{2}{3}\), – \(\frac{1}{5}\), 0.4, 2

(D) – \(\frac{2}{3}\), – \(\frac{1}{5}\), 0.4, 2

Question 5.
What is the absolute value of – 12.5?
(A) 12.5
(B) 1
(C) – 1
(D) – 12.5
Answer:
Absolute value of some number is its distance from 0 on the number line!
|- 12.5| = 12.5

(D) – 12.5

Question 7.
Horatio climbed to the top of a ladder that was 10 feet high. What is the opposite of Horatio’s height on the ladder?
(A) – 10 feet
(B) 10 feet
(C) 0 feet
(D) \(\frac{1}{10}\) foot
Answer:
Opposite of some number is that same number with an added – sign on the left side.
So, in our case, the opposite of 10 is -10 feet.

(A) – 10 feet

Go Math Grade 6 Module 2 Quiz Answers Question 8.
The heights of four students in Mrs. Patel’s class are 5\(\frac{1}{2}\)feet, 5.35 feet, 5\(\frac{4}{10}\) feet, and 5.5 feet. What is the height in feet of the shortest student written as a decimal?
Texas Go Math Grade 6 Module 2 Quiz Answer Key 6
Answer:
Here, we will transform given expressions into decimals and then compare them to reach our solution!
5\(\frac{1}{2}\) = 5 + \(\frac{1}{2}\) = 5 + 0.5 = 5.5
5\(\frac{4}{10}\) = 5 + \(\frac{4}{10}\) = 5 + \(\frac{4 / 2}{10 / 2}\) = 5 + \(\frac{2}{5}\) = 5 + 0.4 = 5.4

Now, when we have them all in the wanted form, we can compare them!
Number 5.5 is greater than 5.4 which is greater than 5.35.
Now we know that the shortest student is 5.35 feet high.
