Question

1m 6dm 2cm + 3m 8dm 5cm ? 55dm 8 cm

Answer 1

Ответ:

1m 6dm 2 cm + 3m 8dm 5 cm= 5m 4dm 7cm= 5,47 m= 54.7 dm= 547 cm

Answer 2

To add the two lengths:

1m 6dm 2cm + 3m 8dm 5cm

First, add the meters, decimeters, and centimeters separately:

Meters: 1m + 3m = 4m Decimeters: 6dm + 8dm = 14dm Centimeters: 2cm + 5cm = 7cm

Now, simplify:

4m 14dm 7cm

Since 1 meter equals 10 decimeters, and 1 decimeter equals 10 centimeters, you can convert the excess decimeters and centimeters to the next higher unit:

4m 14dm 7cm is equivalent to:

4m + 1dm 4cm + 7cm = 4m 5dm 11cm

So, the sum is:

4 meters 5 decimeters 11 centimeters

To further simplify, you can convert some of the decimeters to meters:

4 meters 5 decimeters = 4 meters + 0.5 meters = 4.5 meters

So, the final sum is:

4.5 meters 11 centimeters

So, 1m 6dm 2cm + 3m 8dm 5cm is equal to 4.5 meters 11 centimeters or 55dm 11cm.
