Answer 2

Let's solve the given arithmetic expressions step by step:

1. 98 cm - 23 cm: Subtracting the values, we get: 98 cm - 23 cm = 75 cm.

2. 41 l + 36 l 45 cm: To add these values, we need to convert cm to liters. Since 1 l = 1,000 cm³, we have: 36 l 45 cm = 36,450 cm³ Now we can add the volumes: 41 l + 36,450 cm³ = 41 l + 36.45 l = 77.45 l.

3. 21 l 31 cm + 14 l 29 cm: Similarly, we need to convert cm to liters: 21 l 31 cm = 21,310 cm³ 14 l 29 cm = 14,290 cm³ Adding the volumes: 21 l 31 cm + 14 l 29 cm = 21 l + 14 l + 31 cm³ + 29 cm³ = 35 l + 60 cm³.

4. 95 cm - 63 cm: Subtracting the values, we get: 95 cm - 63 cm = 32 cm.

5. 4 dm 2 cm + 4 dm 7 cm: Since 1 dm = 10 cm, we can convert cm to dm: 4 dm 2 cm = 4 dm + 2 cm = 4 dm + 0.2 dm = 4.2 dm 4 dm 7 cm = 4 dm + 7 cm = 4 dm + 0.7 dm = 4.7 dm Adding the lengths: 4 dm 2 cm + 4 dm 7 cm = 4.2 dm + 4.7 dm = 8.9 dm.

6. 7 dm 6 cm - 5 dm 2 cm: Similarly, we convert cm to dm: 7 dm 6 cm = 7 dm + 6 cm = 7 dm + 0.6 dm = 7.6 dm 5 dm 2 cm = 5 dm + 2 cm = 5 dm + 0.2 dm = 5.2 dm Subtracting the lengths: 7 dm 6 cm - 5 dm 2 cm = 7.6 dm - 5.2 dm = 2.4 dm.

Therefore, the simplified expressions are:

1. 98 cm - 23 cm = 75 cm.
2. 41 l + 36 l 45 cm = 77.45 l.
3. 21 l 31 cm + 14 l 29 cm = 35 l + 60 cm³.
4. 95 cm - 63 cm = 32 cm.
5. 4 dm 2 cm + 4 dm 7 cm = 8.9 dm.
6. 7 dm 6 cm - 5 dm 2 cm = 2.4 dm.
