Mixed Numbers and Improper Fractions
Part A: Fix the Sentence
Each sentence has an error. Rewrite it correctly on the line.
1. Fix the sentence:
5/4 equals 1 and 1/2 because 5 minus 4 is 1 over 2.
Rewrite: 5/4 equals 1 and 1/4 because 5 minus 4 is 1 over the same denominator 4.
2. Fix the sentence:
The number 7/3 is a proper fraction because the top is bigger.
Rewrite: The number 7/3 is an improper fraction because the numerator is greater than the denominator.
3. Fix the sentence:
Two and one half written as an improper fraction is 3/2 because 2 plus 1 is 3.
Rewrite: Two and one half written as an improper fraction is 5/2 because 2 times 2 plus 1 is 5.
Part B: Fill in the Blank
Write the missing word or number on each line.
1. The fraction 6/6 equals exactly 1 whole(s) because the numerator and denominator are the same.
2. Write 9/4 as a mixed number: 9 divided by 4 is 2 with remainder 1, so 9/4 = 2 1/4.
3. Write 1 3/5 as an improper fraction: 1 times 5 plus 3 = 8/5.
4. On a number line, the improper fraction 11/4 sits between the whole numbers 2 and 3.
Part C: Short Answer
Answer each question in one or two complete sentences.
1. Why is 4/4 equal to 1 whole? Explain in your own Grade 4 words.
When the numerator and denominator are the same, every part of the whole has been counted. So 4/4 means all four pieces of one whole are there, which equals exactly 1 whole.
2. Explain the difference between a proper fraction and an improper fraction with an example.
A proper fraction has a numerator smaller than its denominator, like 3/5. An improper fraction has a numerator equal to or larger than its denominator, like 7/5, which is more than one whole.
