Let’s solve each problem step by step. We’re looking for the missing fraction on each number line — that’s where the cupcake is placed.
---
Problem 1:
Number line goes from 0 to 1, divided into 5 equal parts (since we see marks at 1/5, 2/5, 3/5, 4/5).
The cupcake is on the
second mark after 0, which is
2/5.
✔ Missing fraction:
2/5
---
Problem 2:
Number line from 0 to 1, with a mark at 1/2 in the middle.
The cupcake is between 1/2 and 1. Let’s count how many equal parts there are.
From 0 to 1/2 → that’s one half.
From 1/2 to 1 → also one half.
But the cupcake is not at 3/4? Wait — let’s look again.
Actually, if you divide the whole line into 4 equal parts:
- 0
- 1/4
- 2/4 = 1/2
- 3/4 ← this is where the cupcake is!
- 1
Yes! The cupcake is at the third mark out of four →
3/4
✔ Missing fraction:
3/4
---
Problem 3:
Number line from 0 to 1, marked at 1/4, 2/4, 3/4.
Cupcake is on the
first mark after 0 → that’s
1/4
✔ Missing fraction:
1/4
---
Problem 4:
Number line from 0 to 1, divided into 7 equal parts (marks at 1/7, 2/7, ..., 6/7).
Cupcake is on the
sixth mark → that’s
6/7
✔ Missing fraction:
6/7
---
Problem 5:
Number line from 0 to 1, divided into 10 equal parts (marks every 1/10).
Cupcake is on the
third mark after 0 → that’s
3/10
✔ Missing fraction:
3/10
---
Final Answer:
1. 2/5
2. 3/4
3. 1/4
4. 6/7
5. 3/10
