208 см +4 дм 7см=?5м 3 ди 8см- 6 дм 4см=?​

Answer 1

Ответ:

255 см=25 дм 5 см

4м 7 дм 4 см

Answer 2

To solve the given equations, we'll perform the addition and subtraction operations.

1. 208 cm + 4 dm 7 cm: First, let's convert 4 dm to cm. Since 1 dm is equal to 10 cm, 4 dm is equal to 4 * 10 = 40 cm. Now we can add the lengths: 208 cm + 40 cm + 7 cm = 255 cm.

Therefore, 208 cm + 4 dm 7 cm = 255 cm.

2. 5 m 3 dm 8 cm - 6 dm 4 cm: First, let's convert 5 m to cm. Since 1 m is equal to 100 cm, 5 m is equal to 5 * 100 = 500 cm. Next, let's convert 3 dm to cm. Since 1 dm is equal to 10 cm, 3 dm is equal to 3 * 10 = 30 cm. Now we can subtract the lengths: 500 cm + 30 cm + 8 cm - 6 dm - 4 cm. To subtract 6 dm, we need to convert it to cm: 6 dm = 6 * 10 = 60 cm. Now we can subtract the lengths: 500 cm + 30 cm + 8 cm - 60 cm - 4 cm = 474 cm.

Therefore, 5 m 3 dm 8 cm - 6 dm 4 cm = 474 cm.
