Questions

Which is greater: 5/6 or 7/8?
1. 5/6
2. 7/8
3. They are equal
4. Cannot determine
Show answer
Answer: 7/8
5/6 ≈ 0.833; 7/8 = 0.875. Both are close to 1, but 7/8 is larger. Convert: 5/6=20/24, 7/8=21/24. 21/24 > 20/24.
3/5 > 3/7 because fifths are larger pieces than sevenths.
Show answer
Answer: True
Same numerator (3). Fifths (1/5 each) are bigger than sevenths (1/7 each), so 3/5 > 3/7.
1/4 ___ 1/2 (use < or >).
Show answer
Answer: <
1/4 is only one quarter while 1/2 is two quarters. 1/4 < 1/2.
Which fraction is closest to 1 whole?
1. 3/4
2. 5/6
3. 7/8
4. 9/10
Show answer
Answer: 9/10
9/10 is only 1/10 away from 1. It is closer to 1 than 7/8 (1/8 away), 5/6 (1/6 away), or 3/4 (1/4 away).
Compare 4/5 and 6/8. Which is correct?
1. 4/5 < 6/8
2. 4/5 = 6/8
3. 4/5 > 6/8
4. Cannot compare
Show answer
Answer: 4/5 > 6/8
4/5 = 0.8; 6/8 = 0.75. Since 0.8 > 0.75, then 4/5 > 6/8.
2/4 = 1/2
Show answer
Answer: True
2/4 simplifies to 1/2 by dividing both by 2. They are equivalent fractions.
7/10 is greater than 1/2 because 7 is more than ___ of 10.
Show answer
Answer: half
Half of 10 is 5. Since 7 > 5, then 7/10 > 5/10 = 1/2.
Which list shows fractions in order from least to greatest?
1. 3/4, 1/2, 1/4
2. 1/4, 3/4, 1/2
3. 1/4, 1/2, 3/4
4. 1/2, 1/4, 3/4
Show answer
Answer: 1/4, 1/2, 3/4
1/4 = 0.25, 1/2 = 0.50, 3/4 = 0.75. Least to greatest: 1/4, 1/2, 3/4.
5/9 is less than 1/2 because 5 is less than half of 9.
Show answer
Answer: False
Half of 9 is 4.5. Since 5 > 4.5, then 5/9 > 1/2. So 5/9 is NOT less than 1/2.
