Comparing Fractions — Answer Key
Part A: Fill in the Blank
Write the missing word or number on each line.
1. In Grade 3, Maya ate 3/8 of a pizza and Leo ate 5/8, so Leo ate more.
Grade 3 rule: with eighths, 5 pieces beat 3 pieces, so Leo ate more pizza.
2. Grade 3 runners: Ana ran 2/5 mile and Ben ran 2/6 mile, so Ana ran further.
In Grade 3, fifths are larger pieces than sixths, so 2/5 is further than 2/6.
3. In Grade 3 on a number line, 4/6 is to the right of 2/6 because 4 sixths is greater.
Grade 3 number lines place bigger values further right, so 4/6 is right of 2/6.
4. Grade 3 pie chart: 7/10 of a pie is greater than 3/10 of the same pie.
In Grade 3, with equal denominators, 7 tenths is greater than 3 tenths.
5. In Grade 3, Jay drank 1/4 cup and Mia drank 1/3 cup, so Mia drank more.
Grade 3 rule: thirds are bigger pieces than fourths, so 1/3 is more than 1/4.
6. Grade 3 number line: 5/8 sits higher than 2/8 along the same line.
In Grade 3, 5/8 sits at a greater position than 2/8 on the same number line.
7. In Grade 3, Sam colored 4/10 and Tia colored 7/10, so Tia colored more squares.
Grade 3 logic: same tenths denominator, 7 shaded is more than 4 shaded pieces.
8. Grade 3 cake: Rita gave 3/6 of a cake away, which equals one half to friends.
In Grade 3, 3/6 simplifies to 1/2, meaning Rita gave away one half of the cake.
9. In Grade 3 pizza race, Ali ate 2/4 and Ian ate 3/4, so Ian ate more pizza.
Grade 3 comparison: with equal fourths, 3 pieces is more than 2 pieces eaten.
Part B: Matching
Match each item on the left to the correct answer on the right.
1. Match each item to its correct answer.
Grade 3: 5/8 vs 3/8
→ 5/8 is greater than 3/8
5/8 is greater than 3/8
Grade 3: 2/5 vs 2/6
→ 2/5 is greater than 2/6
2/5 is greater than 2/6
Grade 3: 4/10 vs 7/10
→ 7/10 is greater than 4/10
7/10 is greater than 4/10
Grade 3: 3/6 vs 1/2
→ 3/6 equals 1/2
3/6 equals 1/2
Grade 3 matching practice reinforces same-denominator, same-numerator, and equal fraction rules.
