Julio works as a quality control expert in a beverage
factory. The assembly line that he monitors produces about 20,000 bottles in a24-hour period. Julio samples about 120 bottles an hour and rejects the line if he finds more than 1/50 of the sample to be defective. About how many defective
bottles should Julio allow before rejecting the entire line?
I think this is a division problem and how would I start this?
1/50 * 120 = 120/50 = 2 2/5
He should reject the line when he finds 3 defective bottles.
so it is multiplication problem?
Yes. In this kind of construction, a fraction of something is a multiplication problem.
Think of 1/2 of 10. You know it's 5.
1/2 * 10 = 10/2 = 5
