Melodi eats \(\frac{\mathrm{3} }{\mathrm{8}}\) of a pizza and divides the rest between her two friends. What percentage of the pizza do her friends each receive?

If \(\frac{\mathrm{3} }{\mathrm{8}}\) of the pizza is eaten, then 1 - \(\frac{\mathrm{3} }{\mathrm{8}}\) = \(\frac{\mathrm{5} }{\mathrm{8}}\) remains. If that is divided by 2, then each receives \(\frac{\mathrm{5} }{\mathrm{8}}\) ÷2 = \(\frac{\mathrm{5} }{\mathrm{8}}\) x \(\frac{\mathrm{1} }{\mathrm{2}}\) = \(\frac{\mathrm{5} }{\mathrm{16}}\) = 0.3125 = 31.25%.
