Question

65м6дм- 60м, 16м30см-6м,70дм3см+3дм,

Answer 1

1) 5м 6дм
2)10м30см
3)73 дм 3см

Answer 2

Let's solve each of these subtractions and additions separately:

65м6дм - 60м = 5м6дм

16м30см - 6м = 10м30см

70дм3см + 3дм = 73дм3см

So the final result, putting all of these together, is:

5м6дм + 10м30см + 73дм3см = 5м + 10м + 73дм + 6дм + 30см + 3см = 78дм36см

Therefore, the answer is 78дм36см.
