Kimberly is taking three online classes during the summer. She spends 10 hours each week studying for her marketing class, 12 hours studying for her statistics class, and 8 hours studying for her business law class. What percent of her study time does she spend for her statistics class?

The percentage equals hours spent on statistics divided by total hours spent studying for everything.

Calculate total study hours:
Total Study Hours = Marketing Class Study Hours + Statistics Class Study Hours + Business Law Study Hours
Total Study Hours = 10 + 8 + 12
Total Study Hours = 30

Calculate Statistics Study Hours Percentage:
Statistics Study Hours Percentage = Statistics Class Study Hours / Total Study Hours
Statistics Class Study Hours = 8/30

Using our fraction to decimal calculator, we get
Statistics Class Study Hours = 26.67%
