Answer 3

To perform the addition of the given measurements, we need to make sure the units are consistent. Let's convert all the measurements to the same unit and then add them together.

1. Converting the first measurements to millimeters (mm): 5 cm 4 mm = (5 * 10) cm + 4 mm = 50 mm + 4 mm = 54 mm

2. Converting the second measurements to decimeters (dm): 8 m 6 dm = (8 * 10) m + 6 dm = 80 dm + 6 dm = 86 dm

Now, let's add the measurements:

54 mm + 86 dm

Since the units are different, we need to convert one of the measurements to match the other. Let's convert 54 mm to decimeters (dm):

54 mm = 5.4 cm = 0.54 dm

Now, we can add the measurements:

0.54 dm + 86 dm = 86.54 dm

Therefore, the results are:

5 cm 4 mm + 3 cm 2 mm = 54 mm 8 m 6 dm + 7 m 9 dm = 86.54 dm
