First your going to take the whole number 7, 5, and 8 and add them. 7 + 5 + 8 = 20 miles. Then you are going to take 1/5, 1/4, and 2/3 and find a common denominator which is 30. You will then see how many time the number 5, 4, and 3 go into 60. 1/5 x 12/12 = 12/60, 1/4 x 15/15 = 15/60, and 1/3 x 19/19 = 19/60. You will then add 12/60 + 15/60 + 19/60 = 46/60 = 23/30.
