Given the following list of numbers: \frac{3}{5}, \frac{5}{6}, \frac{1}{40}, \frac{2}{3}, \frac{9}{8}, \frac{19}{20} \frac{7}{9}, \frac{3}{4} what is the smallest number subtracted from the biggest number? Express your answer as a decimal.
Find a common denominator, and then compare. You should be able to take things from there.
Sort from the smallest to the largest:
(1 / 40, 3 / 5, 2 / 3, 3 / 4, 7 / 9, 5 / 6, 19 / 20, 9 / 8)
[9/8 - 1/40] =1.10 - difference between the smallest and the largest.
