This one is easy all you have to do is subtract the 2.25 by the 15 to get 12.75.
The answer is C. 30.5% :)
The blank is -8 because -6 +-8=-14+-3=-17.
1.5 cleaner / 12 cups of water
or
1.5 cleaner : 12 cups of water
to reduce this ratio of 1.5:12, we need to divide both by the same number
1.5 divided by 1.5 is 1
12 divided by 1.5 is 8
So the ratio of cleaner to water is 1:8 in its simplest form or 1 part cleaner to 8 parts water.
Hope this helps!! :)
