the teacher student ratio is 3:20. if there are 6 teachers how many kids can attend? if there are 5 teachers how many kids can attend?
Part 1
if there are 6 teachers how many kids can attend?
Applying proportion
3/20=6/x
solve for x
rewrite
20/3=x/6
x=(20/3)*6
x=40 students
Part 2
if there are 5 teachers how many kids can attend?
apllying proportion
3/20=5/x
rewrite
20/3=x/5
solve for x
x=(20/3)*5
x=100/3
x=33.33
therefore
the answer is 33
