Question

5/8 of the 64 musicians in a music contest are guitarist. Some of the guitarist play jazz solos, and the rest play classical solos. The ratio of the number of guitarist playing jazz solos to the total number of guitarist in the contest is 1:4. How many guitarist play classical solos in the contest?

Answer 1

Multiply 5/8 by 64
=40

1:4 means a fourth of them
so basically 10 out of 40

now just subtract 10 from 40 to get the amount of classical players

10 jazz & 30 classical
