See answers below

We have: $3c+2g=8$ For the first gap-width: $3c+2(\frac{5}{8})=8$ $3c+\frac{5}{4}=8$ $c=\frac{9}{4}$ For the second gap-width: $3(2\frac{1}{3})+2g=8$ $7+2g=8$ $g=\frac{1}{2}$ For the third gap-width: $3c+2(\frac{3}{8})=8$ $3c+\frac{3}{4}=8$ $g=\frac{29}{12}$ For the fourth gap-width: $3(2\frac{1}{2})+2g=8$ $\frac{15}{2}+2g=8$ $g=\frac{1}{4}$
