Question

this year mary watched 60 movies. she thought that 54 of them were very good. of the movies she watched, what percentage did she rate as very good?

Explanation:

Step1: Set up percentage formula

$\text{Percentage} = \frac{\text{Number of very good movies}}{\text{Total movies}} \times 100\%$

Step2: Substitute given values

$\text{Percentage} = \frac{54}{60} \times 100\%$

Step3: Calculate the fraction first

$\frac{54}{60} = 0.9$

Step4: Multiply by 100%

$0.9 \times 100\% = 90\%$

Answer:

90
