Three individuals form a partnership and agree to divide the profits equally. X invests $9,000, Y invests $7,000, Z invests $4,000. If the profits are $4,800, how much less
does x receive compared to having the profits divided in proportion to the amounts invested by X, Y, and Z?

So their profits should be divided in the ratio of
9 : 7 : 4
so X will get 9/20 x 4800
Y will get 7/20 x 4800
Z will get 4/20 x 4800
I will let you do the 'buttonpushing' 
2160

X 9/20*4800= 2160
So X should get $ 2160.00
instead of $ 1600.00
X is receiving 21601600= $560 less
