There are b blue jellybeans in the jar, as well as 3/4 b green jelly beans, 5/8 b red jellybeans, 9/16 b white jellybeans, and 7/16 b yellow jellybeans. If there are a total of 216 jellybeans in the jar, how many white jellybeans are in the jar?

PsyDAG,
b + 3/4b + 5/8b + 9/16b + 7/16b = 216
b + 3/4b + 5/8b + b = 216
Solve for b, then 9/16b = ?
