Which ratio would that would create the same orange color ?

Given the following ratio in creating orange color:
[tex]\text{ 4 drops of red : 6 drops of yellow }\rightarrow\text{ 4 : 6}[/tex]Let's check which ratios in the choices will still create the same orange color.
But first, let's simplify the given ratio:
[tex]\text{ 4 : 6 }\rightarrow\text{ }\frac{\text{ 4}}{\text{ 6}}\text{ = }\frac{\text{ }\frac{4}{2}}{\frac{\text{ 6}}{2}}\text{ = }\frac{\text{ 2}}{\text{ 3}}\text{ or 2 : 3}[/tex]Let's now check:
a.) 2 red to 3 yellow
[tex]\text{ 2 read to 3 yellow }\rightarrow\text{ 2 : 3}[/tex]This will create the same orange color.
b.) 40 yellow to 100 red
[tex]\text{ 40 yellow to 100 red }\rightarrow\text{ 100 : 40 = }\frac{\text{ 100}}{\text{ 20}}\text{ : }\frac{\text{ 40}}{\text{ 20}}\text{ = 5 : 2}[/tex]This will not create the same orange color.
c.) 44 red to 66 yellow
[tex]\text{ 44 red to 66 yellow }\rightarrow\text{ 44 : 66 = }\frac{\text{ 44}}{\text{ 22}}\text{ : }\frac{\text{ 66}}{\text{ 22}}\text{ = 2 : 3}[/tex]This will create the same orange color.
d.) 24 red to 26 yellow
[tex]\text{ 24 red to 26 yellow }\rightarrow\text{ 24 : 26 = }\frac{\text{ 24}}{\text{ 2}}\text{ : }\frac{\text{ 26}}{\text{ 2}}\text{ = 12 : 13}[/tex]This will not create the same orange color.
e.) 28 red to 42 yellow
[tex]\text{ 28 red to 42 yellow }\rightarrow\text{ 28 : 42 = }\frac{\text{ 28}}{\text{ 14}}\text{ : }\frac{\text{ 42}}{\text{ 14}}\text{ = 2 : 3}[/tex]This will create the same orange color.
ANSWER: The following ratios will create the same orange color.
2 red to 3 yellow
44 red to 66 yellow
28 red to 42 yellow
