40% of the students in a school band play brass instruments while 4 students play strings instruments

Write an equation that could be used to find how students are in the band if 10 students play brass and string instruments.

10 students (brass) = 40% of band

4 students (strings) = 16% of band

? students (other) = 44% rest of band

14/56%=?/44%

(cross multiply to find?) {don't forget to turn percents into decimals}

?=11

There are 25 students in total in the band.
