You're working on an activity called
“Ordering Fractions”, where you need to place given fractions correctly on number lines from 0 to 1. Since I can’t draw on the number lines for you, I’ll explain
how to order each set of fractions and
where they belong on the number line — so you (and your partner) can confidently place them.

## 🔢 General Strategy:
To compare fractions, you can:
- Convert them to decimals.
- Find a common denominator and compare numerators.
- Use benchmarks like 0, ½, and 1 to estimate positions.
Let’s go problem by problem.
---
🟢 Problem 1:
Fractions: `3/4`, `2/4`, `1/4`
These all have the same denominator → easy!
Compare numerators:
`1/4 < 2/4 < 3/4`
✔ Order: `1/4`, `2/4`, `3/4`
On the number line:
- `1/4` = 0.25 → quarter mark
- `2/4` = 0.5 → halfway
- `3/4` = 0.75 → three-quarters
---
🟢 Problem 2:
Fractions: `4/8`, `4/10`, `4/5`
All have numerator 4 → compare denominators!
The larger the denominator, the smaller the fraction (when numerator is same).
So:
`4/10 < 4/8 < 4/5`
Check with decimals:
- `4/10 = 0.4`
- `4/8 = 0.5`
- `4/5 = 0.8`
✔ Order: `4/10`, `4/8`, `4/5`
On number line:
- `4/10` → 0.4 (a bit less than halfway)
- `4/8` → 0.5 (middle)
- `4/5` → 0.8 (closer to 1)
---
🟢 Problem 3:
Fractions: `3/6`, `1/4`, `2/3`
Convert to decimals or find common denominator.
Decimals:
- `3/6 = 0.5`
- `1/4 = 0.25`
- `2/3 ≈ 0.666...`
✔ Order: `1/4`, `3/6`, `2/3`
On number line:
- `1/4` → 0.25
- `3/6` → 0.5
- `2/3` → ~0.67 (between 0.5 and 1)
---
🟢 Problem 4:
Fractions: `1/10`, `1/2`, `1/5`
Convert to decimals:
- `1/10 = 0.1`
- `1/5 = 0.2`
- `1/2 = 0.5`
✔ Order: `1/10`, `1/5`, `1/2`
On number line:
- `1/10` → very close to 0
- `1/5` → 0.2 (one-fifth)
- `1/2` → middle
---
🟢 Problem 5:
Fractions: `5/7`, `1/3`, `5/10`
Decimals:
- `5/7 ≈ 0.714`
- `1/3 ≈ 0.333`
- `5/10 = 0.5`
✔ Order: `1/3`, `5/10`, `5/7`
On number line:
- `1/3` → ~0.33
- `5/10` → 0.5
- `5/7` → ~0.71 (closer to 1)
---
🟢 Problem 6:
Fractions: `2/10`, `3/4`, `2/8`
Simplify first:
- `2/10 = 1/5 = 0.2`
- `2/8 = 1/4 = 0.25`
- `3/4 = 0.75`
✔ Order: `2/10`, `2/8`, `3/4`
On number line:
- `2/10` → 0.2
- `2/8` → 0.25 (slightly right of 0.2)
- `3/4` → 0.75

2.
4/10, 4/8, 4/5
3.
1/4, 3/6, 2/3
4.
1/10, 1/5, 1/2
5.
1/3, 5/10, 5/7
6.

## 💡 Tip for You & Your Partner:
- Draw small circles or dots on your dry erase board at the correct spots.
- Label each dot with the fraction.
- Compare your placements — if you disagree, convert to decimals together or draw fraction bars (like pie charts) to visualize.
- Then write the final ordered list under each number line as shown above.
You’ve got this! 😊
Parent Tip: Review the logic above to help your child master the concept of fractions on number lines worksheet.
