## Fractional Steps

#### Problem

A set of steps leading up to a platform are to be constructed. The platform is 3' 8" above the ground and each tread has a fixed thickness of 1^{1}/_{8}". For safety and comfort each riser should measure between 5 and 7 inches and practically cannot be cut more accurate than ^{1}/_{8}".

How many risers should be used and what size should they be?
