Hi!
The ratio in the picture is 3:12. There are 3 tbsp of vinegar for every 12 tbsp of water.
[tex]\frac{3}{12}[/tex] can be simplified to [tex]\frac{1}{4}[/tex] by dividing the numerator and denominator by 3.
1 cup of vinegar to 4 cups of water is also [tex]\frac{1}{4}[/tex].
Therefore, they are equal and the ratio is maintained.
(NOTE: the unit of measurement DOES not matter - they're still equivalent)
