[quote=mstcrow5429]How do you attack this problem:
"Apples are collected in a basket for 6 people. One-third, one-fourth, one-eighth, and one-fifth are given to four people, respectively. The fifth person gets tens apples with one apple remaining for the sixth person. Find the original number of apples in the basket."
I came up with 1/3x + 1/4x + 1/8x + 1/5x + 11 = x. After using the least common denominator of 120, adding them up to 109/120x, I had:
109/120x + 11 = x.

Here is the rest of the problem:
Get x on one side of the = sign, 11 = x-109/120x
(convert the 1x to a fraction) 11 = 120/120x - 109/120x
11 = 11/120x
multiply by the reciprical to get 1x and being sure to multiply both sides by this: 120/11 x 11 = 11/120x x 120/11
giving the answer of 120 = x
You can plug in x and see that this is the correct answer.
