Answer:
60%
Explanation:
A percentage is essentially the ratio of part to whole * 100:
Percentage = (part/whole) * 100
Since the 24 movies he rates as very good are part of the 40 movies he watched altogether, we can determine what percentage of 40 is 24 by dividing 24 by 40 and multiplying the quotient by 100:
Percentage = (24/40) * 100
Percentage = (0.6) * 100
Percentage = 60
Thus, Scott rated 60% of the movies he watched as very good.
