                Write a proportion using an unknown value x and the ratio 5:6 then solve it. 
In an orchestra, the ratio of trombones to violas is 1 to 3.
There are 9 violas, Write a proportion that gives the number t of trombones in the orchestra.
How many trombones are in the orchestra?
The school team has 80 swimmers. The ratio of grade 4 swimmers to all swimmers is 5:16. Write a proportion that gives the number s of grade 4 swimmers.

    1. More specifics here are needed. The x could go on either side of the proportion and the x could have a higher value? is there? 
2. 1:3 Ratio (1 Trombone for 3 Violas)
a. 3t = 9
b. 3
3. 5:16 ratio. Multiplying this ratio by 5 nets us 25:80 ratio. There are 25 grade 4 swimmers

    1. 5/6 = x/12 
6 * 2 = 12
5 * 2 = 10
x = 10
does that work?
2. 1/3 = t/9
3 * 3 = 9
1 * 3 = 3
t = 3
so yeah i think we're right
3. i don't quite understand, if you can write it out like how i write out the above answers that'd be great.
