Look at the picture below.
The owner of a piece of land gave the land to his
three children: Lily, Michael and Will. The ratio of the area of land given to
Lily to the area given to Michael to the area given to Will is 7:11:9.
Michaels portion of land is 200 sq. ft. larger than Wills portion. How much
area of land should Michael give to Lily so that all three of them own portions
of the same size?
