Ratios

[Bethanyleigh]

Please help!! I cannot figure out how to solve multiple number ratios!!!!
Ratio: 3parts : 1part : 1part : ½part --- the total amount of liquid is 5 fl oz
I'm not even sure how to word it so that it can ask it properly.. So I attached a photo .. Thank you so very much for any and all help!

3 + 1 + 1 + ½ = 5.5 total parts. <== We need less than the numbers indicate.

5/5.5 = 10/11 <== Yup. That's less than 1, so we'll get less.

3 * 10/11 = 30/11 = 2.727
1 * 10/11 = 10/11 = 0.909
½ * 10/11 = 5/11 = 0.455

2.727 + .909 + .909 + .455 = 5 total parts.

"0.5" is a little unusual. I am somewhat surprised it is not reported as 6:2:2:1 It doesn't matter. We'll get the same solution. It just looks funny to me with that ".5" in there.

6 + 2 + 2 + 1 = 11
5 / 11 = 5/11

6 * 5/11 = 30/11 = 2.727
2 * 5/11 = 10/11 = 0.909
1 * 5/11 = 5/11 = 0.455
