Question

when mixing to colors of paint in equivalent ratios , is the resulting color always the same

Answer 1

We have the following:

The first thing is to calculate the ratio between both paintings.

After finding the ratios, it can be calculated for any value using a proportionality rule.

$\frac{2}{10}=\frac{1}{5}$

for example, for 5 cups of blue paint, should be for yellow paint:

$\begin{gathered} \frac{1}{5}=\frac{5}{x} \\ x=\frac{5\cdot5}{1} \\ x=25 \end{gathered}$

therefore, should be 25 cups of yellow paint
