Question

1м-3дм= 1м-3см= 3дм×4= 1м2дм:6

Answer 1

1 м = 10 дм = 100 см

1 м - 3 дм = 10 дм - 3 дм = 7 дм

1 м - 3 см = 100 см - 3 см = 97 см

3 дм · 4 = 12 дм

1 м 2 дм : 6 = 12 дм : 6 = 2 дм

Answer 2

Let's perform the calculations step by step:

1. 1 meter - 3 decimeters: Since 1 meter is equal to 10 decimeters, we have: 1m - 3dm = 1m - (3/10)m = (10/10)m - (3/10)m = (7/10)m

So, 1 meter - 3 decimeters = 0.7 meters.

2. 1 meter - 3 centimeters: Since 1 meter is equal to 100 centimeters, we have: 1m - 3cm = 1m - (3/100)m = (100/100)m - (3/100)m = (97/100)m

So, 1 meter - 3 centimeters = 0.97 meters.

3. 3 decimeters × 4: 3 decimeters = 0.3 meters. 4 × 0.3 meters = 1.2 meters.

So, 3 decimeters × 4 = 1.2 meters.

4. 1 meter 2 decimeters : 6: 1 meter 2 decimeters is equal to 1.2 meters (since 1 meter is equal to 10 decimeters). 1.2 meters ÷ 6 = 0.2 meters.

So, 1 meter 2 decimeters : 6 = 0.2 meters.

To summarize: 1m - 3dm = 0.7 meters, 1m - 3cm = 0.97 meters, 3dm × 4 = 1.2 meters, 1m 2dm : 6 = 0.2 meters.
