9м-1м 6см-5м 39см: 4м+27дм-1м 83см9м-1м 6см-5м 39см: 4м+27дм-1м 83см

Answer 1

9м-1м 6см-5м 39см= 900 см-106см-539см=255 см= 2 м 55 см
  4м+27дм-1м 83см= 400 см+270 см-183 см= 487 см= 4м8дм7см  

Answer 2

To simplify the given expression, let's combine the like terms.

We have: 9m - 1m + 6cm - 5m + 39cm + 4m + 27dm - 1m + 83cm

First, let's combine the terms with the same units.

The terms with "m" are 9m, -1m, -5m, and 4m. Combining these terms, we have: 9m - 1m - 5m + 4m = 7m

Next, let's combine the terms with "cm": 6cm + 39cm + 83cm = 128cm

Lastly, let's combine the terms with "dm": 27dm = 27dm

Now, let's put it all together: 7m + 128cm + 27dm

Since we have different units (m, cm, dm), it's a good practice to convert them all to the same unit. Let's convert cm to m and dm to m for consistency.

1dm = 0.1m 1cm = 0.01m

Converting 128cm to m: 128cm * 0.01m/cm = 1.28m

Converting 27dm to m: 27dm * 0.1m/dm = 2.7m

Now, let's substitute the converted values back into the expression: 7m + 1.28m + 2.7m

Combining the like terms: 7m + 1.28m + 2.7m = 10.98m

Therefore, the simplified expression is 10.98m.
