Answer 1

1) 7дм 9см–4дм 8см=3дм 1см

2) 9дм 8см–2дм 7см=7дм 1см

Объяснение:

1) 7дм–4дм, 9см–8см

2) 9дм–2дм, 8см–7см

Answer 2

To perform the subtraction, we need to align the units (decimeters, centimeters) and subtract each place value separately. Let's break it down step by step:

First, let's subtract the centimeters:

9 cm - 8 cm = 1 cm

Next, subtract the decimeters:

7 dm - 4 dm = 3 dm

Now, let's subtract the remaining centimeters:

8 cm - 7 cm = 1 cm

Putting it all together, we have:

3 dm 1 cm - 2 dm 1 cm = 1 dm

Therefore, the result is 1 decimeter (1 dm).
