Example 1
There are 4 panes of glass in one window of Landon’s classroom. Each pane of glass is \(\frac{1}{4}\) of the whole window.
How many fourths equal 1 whole?
Place a point on the number line to graph this fraction. The models show that and 1 share the same point and have the same size.
So, 4 fourths = ________________ whole. Or, 
= 1.
Answer:
Given that,
There are 4 panes of glass in one window.
Each pane of glass is \(\frac{1}{4}\) of the whole window.
So, 4 fourths equal to 1 whole or 4/4 = 1.
Example 2
How many wholes are in \(\frac{3}{1}\)?
Think: 
So, 
= \(\frac{3}{1}\) or ___________. There are ____________ wholes in \(\frac{3}{1}\).
Answer:
Given that,
\(\frac{3}{1}\) or 3/1.

How can you tell whether \(\frac{6}{1}\) is greater or less than 1?
Answer:
Given that,
The latex is \(\frac{6}{1}\) = 6/1.
6/1 = 6.
6 is greater than 1.
Therefore \(\frac{6}{1}\) is greater than 1.
Guided Practice
Write a fraction to represent the shaded part of each whole or set of wholes.
Question 1.
Answer:
The fraction to represent the shaded part of each whole is = shaded part/ number of parts
= 8/8 = 1.
Therefore the fraction of the shaded part is 8/8.
Question 2.
Answer:
The fraction to represent the shaded part of each set of wholes is = shaded part/ number of parts
= 4/1
Therefore the fraction of the shaded part is 4/1.
Independent Practice
