Answer:40%
Step-by-step explanation:
lets just forget the number 70 because it wont change anything in this story problem
there must be the value 100% which equals the 70 students
the problem told that 40% of them are sixth graders while 20% are seventh and the rest are eighth so
100-(40+20)=40
if you didnt get it here another way:
40%+20%=60% which is the percentage of seventh and sixth graders together
the rest of the 100% is the eighth so you should subtract the 60% from the 100% which is "40%"
