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
[tex]\frac{x}{y} =\frac{3}{1}\frac{oil}{vinegar}[/tex]
Determine the relation used by Manuela
[tex]\frac{x}{y} =\frac{6}{2}[/tex]
Compare with the recipe
[tex]\frac{3}{1} =\frac{6}{2}[/tex]
[tex]3(2)=6(1)\\6=6[/tex]
Is true, the quantities are proportional
therefore
The quantities used by Manuela were correct
