Fractions: Halves, Thirds, and Fourths — Answer Key
Part A: Multiple Choice
Circle the best answer for each question.
1. A circle is divided into 4 equal parts. One part is shaded. What fraction is shaded?
A) 12
B) 13
C) 14
D) 24
One out of four equal parts is shaded, so the fraction is 14 (one-fourth).
2. Which fraction is the largest?
A) 14
B) 13
C) 12
D) 15
12 is larger than 14. When a whole is divided into fewer parts, each part is bigger.
3. A rectangle is divided into 3 equal parts. Two parts are shaded. What fraction is shaded?
A) 13
B) 23
C) 33
D) 12
Two out of three equal slices were eaten, so the fraction eaten is 23 (two-thirds).
4. Which shape shows one-half shaded?
A) A circle with 1 of 4 parts shaded
B) A square with 1 of 2 parts shaded
C) A rectangle with 1 of 3 parts shaded
D) A triangle with no parts shaded
One-half means 1 out of 2 equal parts is shaded. A square divided into 2 equal parts with 1 shaded shows 12.
Part B: Fill in the Blank
Write the correct answer on each line.
1. If 1 out of 3 equal parts is colored, the fraction is 13.
One out of three equal parts is 13 (one-third).
2. Three-thirds of a shape equals one whole.
When every part is shaded, all the parts together make one complete whole.
3. One-half of 12 is 6.
To find one-half of 12, divide 12 by 2. Half of 12 is 6.
4. One-fourth of 4 is 1.
The top number (numerator) of 14 is 1, which tells us one part is selected.
5. A shape with 2 equal parts that are both shaded shows 22.
Two halves means 2 out of 2 equal parts, written as 22, which equals one whole.
