90см+10см=100см=10дм=1м

Answer 3

To calculate the sum of 90 cm and 10 cm, we simply add the two values together:

90 cm + 10 cm = 100 cm

Now, let's convert this result to decimeters (dm) and meters (m):

1 meter (m) = 10 decimeters (dm) 1 decimeter (dm) = 10 centimeters (cm)

To convert centimeters to decimeters, we divide by 10: 100 cm ÷ 10 = 10 dm

To convert decimeters to meters, we divide by 10: 10 dm ÷ 10 = 1 m

Therefore, the sum of 90 cm and 10 cm is equal to 100 cm, 10 dm, and 1 m.
