Answer 1

30см45мм, 8м-80дм, 18 дм

Answer 2

45мм+30см=30см45мм
8м-62дм=800дм-62 дм=748дм
8м=800дм

Answer 3

Calculation 1: 45mm + 30cm

To calculate the sum of 45mm and 30cm, we need to convert the units to a common unit before adding them together. Let's convert 30cm to millimeters (mm) since both values are in millimeters:

1 centimeter (cm) = 10 millimeters (mm)

Therefore, 30cm = 30 * 10 = 300mm.

Now we can add 45mm and 300mm together:

45mm + 300mm = 345mm.

So, 45mm + 30cm = 345mm.

Calculation 2: 8m - 62dm

To subtract 62 decimeters (dm) from 8 meters (m), we need to convert the units to a common unit before subtracting them. Let's convert 8m to decimeters (dm) since both values are in decimeters:

1 meter (m) = 10 decimeters (dm)

Therefore, 8m = 8 * 10 = 80dm.

Now we can subtract 62dm from 80dm:

8m - 62dm = 80dm - 62dm = 18dm.

So, 8m - 62dm = 18dm.
