The music director can make 15 groups of performers with 6 sixth grade students and 5 seventh grade students in each group.

Step-by-step explanation:

A school chorus has 90 sixth-grade students and 75 seventh-grade students.

Factor these two numbers:

$90=2\cdot 45=2\cdot 3\cdot 15=2\cdot 3\cdot 3\cdot 5\\ \\75=3\cdot 25=3\cdot 5\cdot 5$

Find GCF(90,75):

$GCF(90,75)=3\cdot 5=15$

Now,

$90=15\cdot 6\\ \\75=15\cdot 5$

Therefore, the music director can make 15 groups of performers with 6 sixth grade students and 5 seventh grade students in each group.
