Answer 2

To perform this arithmetic operation, you need to add and subtract the given measurements. Let's break it down step by step:

First, let's add and subtract the measurements in each unit:

1. Add the measurements in decimeters (dm):

   • (7 dm + 4 dm) = 11 dm
   • (2 m - 5 dm) = -3 dm

2. Add the measurements in centimeters (cm):

   • (5 cm + 2 cm - 8 cm) = -1 cm

3. Add the measurements in millimeters (mm):

   • (3 mm - 27 mm) = -24 mm

Now, let's combine the results:

• The total measurement in decimeters (dm) is 11 dm - 3 dm = 8 dm.
• The total measurement in centimeters (cm) is -1 cm.
• The total measurement in millimeters (mm) is -24 mm.

Now, let's convert these measurements back to the mixed unit format:

• 8 dm = 8 dm
• -1 cm = -1 cm
• -24 mm = -2 cm and -4 mm (since there are 10 mm in 1 cm)

So, the final result in mixed unit format is: 8 dm - 1 cm - 4 mm
