Answer 2

Calculations

To solve these mathematical expressions, let's break them down one by one:

1. 500m2:2 - The expression "500m2:2" can be interpreted as "500 square meters divided by 2." - The result of this expression is 250 square meters.

2. 2a × 360 - The expression "2a × 360" involves a variable "a" and multiplication by 360. - Without the specific value of "a," it's not possible to provide a numerical result for this expression.

3. 560cm:2 - The expression "560cm:2" can be interpreted as "560 square centimeters divided by 2." - The result of this expression is 280 square centimeters.

4. 444mm×2 - The expression "444mm×2" means "444 millimeters multiplied by 2." - The result of this expression is 888 millimeters.

5. 564cm + 30dm - To add 564 centimeters and 30 decimeters, we need to convert them to the same unit. - 30 decimeters is equal to 300 centimeters, so the total is 564 cm + 300 cm = 864 centimeters.

6. 1km - 30dm 5cm - To subtract 30 decimeters and 5 centimeters from 1 kilometer, we need to convert all units to the same. - 30 decimeters is 3000 centimeters, and 5 centimeters is 5 centimeters. - So, 1 kilometer - 3000 centimeters - 5 centimeters = 997 kilometers and 995 centimeters.
