Fraction Darts
The object of the Fraction Darts challenge is to "pop" balloons located on a number line between 0 and 1. The darts are "thrown" by entering a number in fractional form.  Here is a glimpse of a game in progress. Two darts (5/8 and 3/4) have been thrown so far. Notice that 3/4 is too big and 5/8 is too small. What is your next throw?
