Answer 2

To solve these equations, we need to perform subtraction with mixed units. Let's calculate each equation step by step:

1. 1 meter - 6 decimeters: Since 1 meter is equal to 10 decimeters, we can rewrite the equation as: 10 dm - 6 dm = 4 dm. Therefore, 1 meter - 6 decimeters is equal to 4 decimeters.

2. 1 meter - 2 decimeters 7 centimeters: First, we need to convert centimeters to decimeters. 7 cm is equal to 0.7 dm. Now, we can perform the subtraction: 1 meter - 2 decimeters - 0.7 decimeters = 1 meter - 2.7 decimeters. Since 1 meter is equal to 10 decimeters, we can rewrite the equation as: 10 dm - 2.7 dm = 7.3 dm. Therefore, 1 meter - 2 decimeters 7 centimeters is equal to 7 decimeters and 3 centimeters.

3. 4 meters - 1 meter 8 decimeters: First, we need to convert decimeters to meters. 8 dm is equal to 0.8 meters. Now, we can perform the subtraction: 4 meters - 1 meter - 0.8 meters = 4 meters - 1.8 meters. Therefore, 4 meters - 1 meter 8 decimeters is equal to 2.2 meters.

4. 3 decimeters 2 centimeters - 1 decimeter 9 centimeters: First, we need to convert centimeters to decimeters. 2 cm is equal to 0.2 dm, and 9 cm is equal to 0.9 dm. Now, we can perform the subtraction: 3 decimeters 2 centimeters - 1 decimeter 9 centimeters = 3 decimeters - 1 decimeter - 0.2 decimeters + 0.9 decimeters. Simplifying the equation, we have: 2 decimeters + 0.7 decimeters = 2.7 decimeters. Therefore, 3 decimeters 2 centimeters - 1 decimeter 9 centimeters is equal to 2 decimeters and 7 centimeters.
