1 one can + 3 cans of water= 4 oz, also we can set up a ratio using these numbers 1/3 . 12 ounce cans + x water = x 0z. Now we can find out how much water is needed. 1/3 x 12/x; x= 36, hence 12/36= 48 oz. now we need to know 12 ounce cans of the concentration are required to prepare 200-6 ounce serv...

75 is multiple of 5, os square of 5= 25,
25 - 75 = 50; we know that square of 7= 49, rest 1, so square of 1=1

5 + 7 + 1 =13.

The trick is known the multiple of 75, then you can figure out the rest.

How did you get W:C:M => 25:10:12; i don't know how to calculate this.
Can you explain please?

We can make things simpler...
If xy=1; it tells that x=1 and y=1, right?

so, 2^(1+1)^2/2^(1-1)^2=
2^2^2/2^0^2=
2^4/2^0=
16/1= 16

Very simple we put numbers.
