Question

20л + 500см3 - 2дм3=? ​

Answer 1

Ответ:

Пошаговое объяснение:

20 л  = 20 дм³

500 см³= 0,5 дм³

20 дм³ + 0,5 дм³ - 2 дм³= 18,5 дм³​

Answer 2

To solve this equation, we need to convert all the measurements to the same unit. Let's convert everything to liters (L):

1 cm³ = 1/1000 L 1 dm³ = 1 L

Given: 20 L + 500 cm³ - 2 dm³ = ?

Converting 500 cm³ to liters: 500 cm³ * (1 L / 1000 cm³) = 0.5 L

Converting 2 dm³ to liters: 2 dm³ * 1 L = 2 L

Now we can substitute the values back into the equation: 20 L + 0.5 L - 2 L = 18.5 L

Therefore, 20 L + 500 cm³ - 2 dm³ is equal to 18.5 L.
