Understanding Fractions — Answer Key
Part A: Fix the Sentence
Each sentence has an error. Rewrite it correctly on the line.
1. Fix the sentence:
In the fraction 34, the number 4 is the numerator.
Corrected: In the fraction 34, the number 4 is the denominator.
The corrected sentence is: "In the fraction 34, the number 4 is the denominator.". The original sentence "In the fraction 34, the number 4 is the numerator." contained an error that needed to be fixed.
2. Fix the sentence:
13 is greater than 12 because 3 is more than 2.
Corrected: 13 is less than 12 because thirds are smaller parts than halves.
The corrected sentence is: "13 is less than 12 because thirds are smaller parts than halves.". The original sentence "13 is greater than 12 because 3 is more than 2." contained an error that needed to be fixed.
3. Fix the sentence:
A fraction with 0 as the numerator equals 1.
Corrected: A fraction with 0 as the numerator equals 0.
The corrected sentence is: "A fraction with 0 as the numerator equals 0.". The original sentence "A fraction with 0 as the numerator equals 1." contained an error that needed to be fixed.
Part B: Fill in the Blank
Write the missing word or number on each line.
1. In the fraction 58, the numerator is 5.
The numerator is the top number in a fraction. In 58, the numerator is 5.
2. A fraction shows equal parts of a whole.
A fraction represents equal parts of a whole.
3. The bottom number of a fraction is the denominator.
The denominator is the bottom number of a fraction and tells how many equal parts the whole is divided into.
4. If a pizza is cut into 4 equal slices and you eat 1, you ate 14 of the pizza.
Eating 1 out of 4 equal slices means you ate 14 of the pizza.
Part C: True or False?
Read each statement. Circle True or False.
1. The fraction 25 means 2 equal parts out of 5.
True False
The statement is true based on fraction concepts.
2. The denominator tells how many parts are shaded.
True False
The statement is false; check the fraction concept carefully.
3. 12 of a shape means the shape is split into 2 equal parts.
True False
The statement is true based on fraction concepts.
