Answer 3

To solve the given addition problems, let's first convert all the measurements to a consistent unit. Let's use centimeters (cm) for this calculation.

1. Converting the measurements: 5 cm + 6 mm = 5 cm + 0.6 cm = 5.6 cm 9 mm = 0.9 cm

2. Adding the measurements: 5.6 cm + 0.9 cm = 6.5 cm

Now let's move on to the second problem:

1 m - 6 dm = 10 dm - 6 dm = 4 dm 3 dm = 30 cm 8 cm = 8 cm

Adding the measurements: 4 dm + 30 cm + 8 cm = 4 dm + 38 cm

Since the units are not the same, we need to convert dm to cm: 1 dm = 10 cm

4 dm + 38 cm = 40 cm + 38 cm = 78 cm

Finally, let's solve the third problem:

3 dm = 30 cm 7 cm = 7 cm

Adding the measurements: 30 cm + 7 cm = 37 cm

So, the results are:

1. 5 cm + 6 mm + 9 mm = 6.5 cm
2. 1 m - 6 dm + 3 dm 8 cm + 7 cm = 78 cm
3. 3 dm 8 cm + 7 cm = 37 cm
