Answer 1

2 Дм 2 см=22 см.
1 м = 100 см
100-22= 78
2 дм 2 см + 7 дм 8 см = 1 м

Answer 2

2дм 2см=22см
100см-22см=78см
Получается:
2дм 2см+7дм 8см=1м

Answer 3

To find the missing value, we need to perform unit conversions so that all the measurements are in the same unit.

1 meter (m) = 10 decimeters (dm) = 100 centimeters (cm)

Let's convert the given measurements to centimeters:

2 dm = 2 * 10 cm = 20 cm 2 cm = 2 cm

Now, we can add the converted measurements:

20 cm + 2 cm = 22 cm

So, the missing value is 22 cm.
