Answer 1

Ответ:

Пошаговое объяснение:

800 а ÷ 2 =  400 а

1000 см3-1 дм3=  1000см3 -1000 см3=0 (1 дм3 = 1 000 см3)

400м2÷2= 200 м2

Answer 2

Ответ:

800а÷2=400а

1000см3-1дм3=0см3

400м2÷2=100м2

Answer 3

Looks like you've provided a series of mathematical expressions. Let's break down each one:

1. 800а ÷ 2: I'm not sure what "а" represents, as it seems to be a variable or a placeholder. If "а" is a number, then you can simply divide 800 by 2 to get the result.

2. 1000см3 - 1дм3: This appears to be a subtraction of volumes. 1 cubic decimeter (дм3) is equal to 1000 cubic centimeters (см3), so subtracting 1000см3 from 1дм3 would result in 0.

3. 400м2 ÷ 2: This is a division of area. Dividing 400 square meters (м2) by 2 would result in 200 square meters.

If you could provide more context or clarify the values of the variables, I could give you more accurate answers.
