Lesson 8.5
Write the fraction that names the point.
Question 1.
point A: \(\frac{□} {□}\)
Answer: \(\frac{1} {6}\)
Explanation:
The number lies between 0 and 1. Each point is 1 sixth of the number line. So, it starts with 0/6 and ends on 6/6.
Now we have to locate the point A.
The point A lies between 0/6 and 2/6. The number between 0 and 2 is 1.
Thus the point A is \(\frac{1} {6}\)
Question 2.
point B: \(\frac{□} {□}\)
Answer: \(\frac{3} {6}\)
Explanation:
The point B lies between \(\frac{2} {6}\) and \(\frac{4} {6}\). The number between 2 and 4 is 3. Thus the location of point B is \(\frac{3} {6}\).
Question 3.
point C: \(\frac{□} {□}\)
Answer: \(\frac{5} {6}\)
Explanation:
The point C is located between \(\frac{4} {6}\) and \(\frac{6} {6}\).
The number between 4 and 6 is 5. Thus the location of Point C is \(\frac{5} {6}\)
Lesson 8.6
Each shape is 1 whole. Write a fraction greater than 1 for the parts that are shaded.
Question 4.
2 = \(\frac{□} {□}\)
Answer: \(\frac{8} {4}\)
Explanation:
There are 2 circles and each circle is equally divided into 4 groups.
Number in each group = 4
Number of equal parts = 8
The shaded part of the circle = \(\frac{8} {4}\)
Question 5.
3 = \(\frac{□} {□}\)
Answer: \(\frac{18} {6}\)
Explanation:
Number of circles = 3
Number of equal parts = 18
Number of shaded part in each circle = 6
So, the fraction of the shaded part is \(\frac{18} {6}\)
Lesson 8.7
Write a fraction to name the shaded part of each group.
Question 6.
\(\frac{□} {□}\)
Answer: \(\frac{3} {6}\) or \(\frac{1} {2}\)
Explanation:
There are 6 circles, in which 3 circles are shaded and 3 circles are not shaded.
So, the fraction name for the shaded part is \(\frac{3} {6}\) or \(\frac{1} {2}\)
Question 7.
\(\frac{□} {□}\)
Answer: \(\frac{1} {4}\) or \(\frac{2} {8}\)
Explanation:
The figure shows that there are 8 circles and in that 2 circles are shaded.
So, the fraction name for the shaded part is \(\frac{2} {8}\) or \(\frac{1} {4}\)

Question 8.
Charlotte has 12 T-shirts. One-fourth of her T-shirts is green. How many of Charlotte’s T-shirts are green?
_________ green T-shirts
Answer: 3 T-shirts
Explanation:
Given,
Charlotte has 12 T-shirts.
One-fourth of her T-shirts is green.
To know how many of Charlotte’s T-shirts are green we need to multiply 12 with 1/4
12 × \(\frac{1} {4}\)
12/4 = 3
Therefore there are 3 green T-shirts.
Question 9.
Josh walks 18 dogs each week. Today, he is walking \(\frac{1}{3}\) of the dogs. How many dogs is he walking today?
