Answer 2

To add these two lengths together, you can start by adding the units separately and then carry over any excess units from one unit to the next. Here's how you can do it:

3 meters (m) + 2 decimeters (dm) = 3 meters + 0.2 meters = 3.2 meters

Next, add the centimeters (cm):

78 centimeters (cm) + 56 centimeters (cm) = 78 cm + 56 cm = 134 cm

Now, you need to carry over any excess centimeters to the decimeters:

134 cm is equivalent to 1 decimeter (dm) and 34 centimeters (cm).

So, add the carried-over decimeter to the decimeters from the previous step:

2 dm + 1 dm = 3 dm

Now, you have the result in meters and decimeters, which is 3 meters and 3 decimeters. You can also convert this to meters if you prefer:

3 meters + 3 decimeters = 3.3 meters

So, the sum of 3 meters 5 decimeters 78 centimeters and 2 decimeters 56 centimeters is 3 meters 3 decimeters 34 centimeters, or 3.334 meters.
