Problem: what is the answer to this ratio question?
I am stuck on this Math and Focus question and it's hard.I don't understand the problem.Here's the problem,A cleaning and water are mixed in the ratio 4:15.The amount of the water in the mixture is 1,200 milliliters.What is the total volume of the mixture? I hope you got it crying sad
Ratios are fractions. The ratio 4:15 is the same as 4/15. What it
is saying is that for every 4 parts of one item, there are 15 parts of the other.
The problem says "a cleaning (product) and water are mixed in the ratio of 4:15"
Because the cleaning product is stated first, it is equivalent to the value of 4;
the water is equivalent the value of 15.
We don't know how much of the cleaning product was used, so we call that x.
The amount of water was 1200 ml.
We can construct our fraction as x/1200. Since that has to be in the
ration of 4:15, we have x/1200 = 4/15. Solve that for x.
x/1200 = 4/15
(x/1200) * 1200 = (4/15) * 1200
x = 4800/15
x = 320
So, 320ml of cleaning product was added to 1200ml of water. Together,
that is 320ml + 1200ml = 1520ml.
