20.8kgs equals 20l, what is 10.5 kgs in litres

Y = k x

20.8 kg = 20L
10.5 kg = ?L

Independent variable (y) : 20.8 kg
Dependent variable (x) : 20L

Find k, or a number that will be multiplied to the dependent variable to produce the independent variable.

20.8 kg = k (20L)
20.8 kg ÷ 20L = k
k = 1.04

Use k to find the dependent variable in the second set of items.

10.5 kg = (1.04) x
10.5 kg ÷ 1.04 = x

The answer would be:
10.1L
