Nady [450]

Answer:

The quantities used by Manuela were correct

Step-by-step explanation:

The question is

Did Manuela use the right quantities?

Let

x -----> the parts of oil

y ----> the parts of vinegar

we know that

The ratio of the parts of oil by the parts of vinegar of recipe is

$\frac{x}{y} =\frac{3}{1}\frac{oil}{vinegar}$

Determine the relation used by Manuela

$\frac{x}{y} =\frac{6}{2}$

Compare with the recipe

$\frac{3}{1} =\frac{6}{2}$

$3(2)=6(1)\\6=6$

Is true, the quantities are proportional

therefore

The quantities used by Manuela were correct
