First change the mixed fraction to improper fraction, and then find common denominators.


5 1/2 = 11/2


4/9(2/2) = 8/18

11/2(9/9) = 99/18

-------------------------------------------------------------------------------------------------------------------

Next, subtract


99/18 - 8/18 = 91/18


91/18 = 5.05


-------------------------------------------------------------------------------------------------------------------

As you are finding the best estimate, 5.05 is closest to 5, which makes your answer D)

Vesnalui [34]
  1. You have to find the total number of computers to find the denominator: 72 + 112 + 711 = 895.
  2. To find the probability, you just have to set the number of the different kinds of computers as the numerator:
  • 72/895 = 0.080
  • 112/895 = 0.125
  • 711/895 = 0.794
