Mixing paint with water

Mr. Adamek will paint. The purchased paint is diluted with water in a ratio of 1: 1.5.

a) how many parts of water will add to 1 part of the paint
b) how many liters of water the mission adds to 2 liters of paint

Correct result:

a =  1.5
b =  3 l

Solution:

$a=1.5=\dfrac{ 3 }{ 2 }$

$$\begin{gathered} V_1=2\text{ l } \\ b=V_1\cdot a=2\cdot 1.5=3\text{ l} \end{gathered}$$
