Answer

Piano: $$\frac{1}{20} $$ Guitar: $$\frac{1}{10} $$ Woodwinds: $$\frac{1}{8}$$ Drums: $$ \frac{1}{6}$$ Strings: $$ \frac{1}{3}$$

Work Step by Step

We divide the number of the bass by the number of each of the other 5 instruments to find the 5 requested ratios. Doing this, we find: Piano: $$ =\frac{5}{100} \\ =\frac{1}{20} $$ Guitar: $$ =\frac{5}{50} \\ =\frac{1}{10} $$ Woodwinds: $$ =\frac{5}{40} \\ =\frac{1}{8}$$ Drums: $$ =\frac{5}{30} \\ =\frac{1}{6}$$ Strings: $$ =\frac{5}{15} \\ =\frac{1}{3}$$
