Question

3дес.+7дес.=?дес.=?сот. 3дм.+7дм.=?дм.=?м.

Answer 1

3дес.+7дес.=10дес.=1сот.
3дм.+7дм.=10дм.=1м.

Answer 2

To calculate the sum of 3 decimeters (3 dm) and 7 decimeters (7 dm), we simply add the numbers together:

3 dm + 7 dm = 10 dm

Therefore, the sum of 3 decimeters and 7 decimeters is 10 decimeters.

To convert decimeters (dm) to meters (m), we divide by 10 since there are 10 decimeters in 1 meter:

10 dm / 10 = 1 m

Therefore, the sum of 3 decimeters and 7 decimeters is equal to 1 meter.

To convert meters (m) to centimeters (cm), we multiply by 100 since there are 100 centimeters in 1 meter:

1 m * 100 = 100 cm

Therefore, the sum of 3 decimeters and 7 decimeters is equal to 1 meter or 100 centimeters.
