Educational worksheet for children to practice reading scales and measuring the weight of fruit pieces in grams.

Explanation:
We need to read the weight shown on each scale. Each scale has a dial marked in grams (g), from 0 to 50, with numbers every 10 grams and smaller marks for each gram.

Let’s go one by one:

1. Half an apple:
The needle points exactly halfway between 40 and 50 — that’s 45 g.
✔ So half an apple = 45 g

2. Slice of orange:
The needle points exactly at 30.
✔ So slice of orange = 30 g

3. A cherry:
The needle points at 20.
✔ So a cherry = 20 g

4. Piece of pineapple:
The needle points at 10.
✔ So piece of pineapple = 10 g

Double-check each:
- Scale 1: Between 40 and 50 → middle is 45 ✔️
- Scale 2: Directly on 30 ✔️
- Scale 3: Directly on 20 ✔️
- Scale 4: Directly on 10 ✔️

All readings are clear and unambiguous.

Final Answer:
1. 45
2. 30
3. 20
4. 10
