Answer:

Step-by-step explanation:

Set this up as a proportion with the ratios being

$\frac{vinegar}{oil}$ If there is a 2:5 ratio of vinegar to oil, that ratio looks like this:

$\frac{v}{o}:\frac{2}{5}$ and if we are looking for how much oil, x, is needed for 20 ml of vinegar, then that ratio completes the proportion:

$\frac{v}{o}:\frac{2}{5}=\frac{20}{x}$ and cross multiply.

2x = 100 so

x = 50 ml of oil
