**In the high school band, there are 2 percussionists on the sideline for every 13 marching instruments If the high school band has 150 total members how many percussionists are on the sideline? **

The ratio of percussionists to total band members is 2:(2+13), or 2:15.

As ratios are equal to fractions, we can put this in an equation:

\({2\over15}={x\over150}\).

Cross-multiply to solve:

\(300=15x\)

\(20=x\).

\(\boxed{\textbf{There are 20 percussionists on the sideline.}}\)

Hope this helped,
