Kim made 1 1/4 quarts of a fruit smoothie. she drank 1/5 of the smoothie. her brothers drank the rest of the smoothie. they each had 1/3 quart how many brothers does kim have ?

Now, she made 1 and 1/4 quart of smoothie, she got thirsty and drank 1/5 of that, now how much is 1/5 of 1 and 1/4?  well, just the product,



notice, is really just 5/4 of smoothie, she drank 1/4, so, what's leftover is 4/4 then, 5/4 - 1/4 is just 4/4, or really just 1.

now, her brothers drank the rest, well, the rest is 4/4, ok.... and each drank 1/3 of the smoothie, how many times does 1/3 go into 4/4?

The answer is: y would equal 3 because if you simplify the equation then it would be y= 3x+9 and if you divide 3x and 9 by 3 it would equal 3. y= 3
