Answer 2

To solve the given addition problems, we need to add the lengths together. Let's start with the first problem:

3m 8dm + 6m 2dm - 7m 7dm

First, we can add the meters, then the decimeters separately. Let's start with the meters:

3m + 6m - 7m = 2m

Now, let's add the decimeters:

8dm + 2dm - 7dm = 3dm

Putting it together, we have:

2m 3dm

Now, let's move on to the second problem:

5dm 2cm - 19cm + 3dm 6cm + 3dm 1cm

First, let's add the centimeters:

2cm - 19cm + 6cm + 1cm = -10cm

Now, let's add the decimeters:

5dm + 3dm + 3dm = 11dm

Putting it together, we have:

11dm - 10cm

It's important to note that we cannot directly add decimeters and centimeters together. If you need the final result in a consistent unit, you can convert centimeters to decimeters. Since 1 decimeter is equal to 10 centimeters, we can convert the centimeters to decimeters:

-10cm = -1dm

Now, we have:

11dm - 1dm = 10dm

Therefore, the final result is:

10dm
