1 answer

a. Jessie's error is in the last step where she multiplied the fractions incorrectly. Instead of multiplying the numerators (17 and 3) and the denominators (5 and 10), she multiplied the whole numbers (17 and 3) and then the fractions (5 and 10).

b. The correct answer is:

(17/5) * (3/10) = (51/50) or 1 1/50
