Dr. Norman saw 990 patients last year. This year, the number of patients she saw was 10% lower. How many patients did Dr. Norman see this year?

891 patients

Step-by-step explanation:

10% of 990 is 99. If you want to calculate 10% of a number you just divide it b 10, and 990/10=99. From there you subtract 99 from 990, which gives you 891.
