The ratio (by volume) of milk in a certain solution is 3 to 8. if the total volume of the solution is 187 cubic feet, what is the volume of water in the solution? explain. (16 pts and brainliest)

We know that the total volume of the solution is 187 cubic feet.
187=3x+8x
187=11x
17=x
Now we know that the ratio 3 to 8 is 51 to 136.
Double check, (3*17)+(8*17)=187.
I'm not sure which part of the ratio is water, but knowing this information, you should be able to solve it. I believe it may be this:
The total volume of milk is 51. If the rest of the solution is water, then 187-51=136.

That is the answer to your question
