1 / 20
1) A ribbon is 3/4 meter long. If Meena uses 1/2 meter, how much ribbon is left?
3/4 − 1/2 = (3/4 − 2/4) = 1/4
2 / 20
2) Select the INCORRECT option.
5/10 = 0.5, 4/8 = 0.5 → both equal 1/2.
3 / 20
3) A student simplified 6/12 and wrote 3/6.
What better he could have done?
6/12 simplifies to 1/2, not 3/6. 3/6 = 1/2 but not the correct simplification from 6/12 directly.
4 / 20
4) In a fruit bowl, 1/5 of the fruits are bananas, 2/5 are apples, and the rest are oranges.
🍌🍎🍎🍊🍊
What fraction of the fruits are oranges?
1/5 + 2/5 = 3/5 → Oranges = 1 − 3/5 = 2/5.
5 / 20
5) Which fraction is closest to 1 but not equal to it?
5/6 ≈ 0.83, very close to 1 but not equal.
6 / 20
6) Ravi has 3/4 of a chocolate bar 🍫.
He gave 1/2 of what he had to his sister.
How much does he have now?
1/2 of 3/4 = 3/8 → Ravi gave away 3/8. Remaining = 3/4 − 3/8 = 6/8 − 3/8 = 3/8
7 / 20
7) A student says 4/8 is not equal to 1/2 because 4 ≠ 1. Is the student correct?
4/8 = 0.5 and 1/2 = 0.5 → They are equivalent even though numerators are different.
8 / 20
8) Which of the following shows the same part shaded as 2/4?
2/4 is the same as 1/2. Option C shows exactly that.
9 / 20
9) A student said 3/9 = 1/3 because both are “small fractions.”
What is the mistake?
3/9 = 1/3, 2/6 = 1/3 → Actually, they **are equal** → So, the **student is correct**, but the reasoning is wrong → correct answer is (B): They are not equal **because the student guessed**
10 / 20
10) Rishi has 🚗🚗🚗🚗🚗🚗🚗🚗🚗🚗🚗🚗🚗🚗🚗🚗🚗🚗 toy cars.
If 3/6 of them are battery cars, how many are without battery?
3/6 of 18 = 9 red cars → Not red = 18 − 9 = 9
11 / 20
11) A jug holds 2 liters of juice.
Ria drinks 1/2 liter each time.
How many times can she drink from the jug?
2 ÷ 1/2 = 4. She can drink 4 times (0.5 L × 4 = 2 L).
12 / 20
12) A rope is 12 meters long. If you cut off 1/3 of it, how much is left?
1/3 of 12 = 4 → Remaining = 12 − 4 = 8 meters
13 / 20
13) Ria drank 3 out of 8 glasses of water today.
What fraction of water did she not drink?
8 total – 3 drank = 5 left → 5/8 not drunk.
14 / 20
14) A watermelon was cut into 10 equal pieces.
John ate 3, and Tina ate 2.
What fraction of the watermelon is left?
3 + 2 = 5 pieces eaten → 10 − 5 = 5 left → 5/10
15 / 20
15) Which of the options is equal to 2/6?
2/6 = 1/3 after dividing both by 2
16 / 20
16) Which fraction is the smallest among the following?
1/2 = 0.50, 5/8 = 0.625, 2/3 ≈ 0.66, 3/4 = 0.75 → smallest is 1/2.
17 / 20
17) If 6/12 = 1/2, then which fraction is also equal to 1/2?
5/10 = 0.5 = 1/2.
