5м4дм-17дм=         5м14дм+1м67см

Answer 1

????????????????¿????

Answer 2

1)5м4дм-17дм=540см-170см=3м 70дм
2)5м 14дм+1м 67см=514см+167см=6м 81дм

Answer 3

To subtract 17 dm from 5m 4dm, we need to borrow 1 meter from the 5 meters to have 4m10dm. Then we subtract 1 dm from the 10 dm to have 9 dm, giving us the result of 4m9dm.

To add 5m14dm and 1m67cm, we need to convert 1m67cm to dm by dividing by 10, giving us 0.167dm. Then we add 5m14dm and 0.167dm to get 5m14.167dm.

Therefore, the equation 5м4дм-17дм = 4м9дм is true, but it is not equal to 5м14дм+1м67см. Instead, 5м14дм+1м67см is equal to 5м14.167дм.
