Answer to Question 1

0.85 and 17/20

Global Rationale: To convert percentages to a fraction place the value of the percent in the numerator and the 100 as the denominator. For 85 this would be 85/100. Reduce this number further by dividing by 5 to determine the smallest fraction as being 17/20. To determine the decimal number begin again by placing 85 as the numerator and 100 as the denominator or 85/100. Since the denominator is 100, the number has 2 decimal points or 0.85.

Answer to Question 2

1,2,3,4

Rationale 1: A basic four-function (addition, subtraction, multiplication, and division),
handheld calculator with a square-root key is sufficient to perform most medical dosage calculations. While having a percentage function may be useful, this is not required when calculating drug dosages.
