Find a common denominator (hint: multiplying the denominators always finds a common factor- not always the least common denominator but it works with any common factor) for 1/3, 1/4, and 1/5. Add those 3 figures together and subtract from 1 to get the fraction of people who make more than $100,000 per year.
Or if you don't have to show work just use a calculator 1-(1/3)-(1/4)-(1/5) and convert the answer to a fraction.
