I have a really bad problem. What's the difference between Ratios and Proportions?
And how do you rewritte the fraction so tat the numerador and the denominator have the same units then simplify? :
2 qt / 4 gal.
I'll really really appreciate your help to a stupid person like me. (I suck in math)

you have to come up with like units first. the smaller unit is quarts, so you have to figure out how many quarts are in 1 gallon. there are 4 quarts in 1 gallon, then there are 16 quarts in 4 gallons.
2 qt/ 16 qts = 1/8
divide numerator and denominator by (2)

Changing to the same units first, there are 4 quarts to each gal, so you multiply he 4 quarts X 4 = 16 quarts
So 4 gallons = 16 quarts
so now your fraction? looks like this 2qts/16 qts
Now you can simplify 2/16 by dividing the numerator and the denominator by the same number. In this case divide each by 2.
2/2 = 1, 2/16 = 8
1/8

Well, there are 4 quarts per gallon, so you simplify like this:
2 qt / (4 gal * 4 qt/gal)
= 2 qt / (4 * 4 qt * gal / gal) Gallons over gallons is 1, so:
= 2 qt / 16 qt
= 1/8
Ratios and proportions are very closely related concepts, as you can see from the dictionary entry on each one referring to the other.

proportion is a statement of equality between two ratios. Four quantities, a, b, c, d, are said to be in proportion if a/b = c/d.
ratio is the relation between two similar magnitudes with respect to the number of times the first contains the second: the ratio of 5 to 2, written 5:2 or 5/2.
2qt/4gal
you mutiply the gallons by 4 to equal to quarts which is:
2qt/16qt
Then you reduce to get 1/8

ratios are like there is a 1 to 2 chance of winning. proportions are like 3/4 =x/8. It may seem confusing at first, but they are really completely different.
