Hellp that's is hard for me to figure out and i tried to do these two my self but its kinda hard

65. change 11 5/6 to a mixed number:

71/6-17/18
multiply 6 and 71 by 3 which equals 18 so now the denominators are the same

213/18-17/18=196/18
to simplify divide 196 and 18 by 2

196÷2=98
  18÷2=9
now divide 98 by 9

98÷9=10 (rounded to whole number)
9×10=90
so to get 98 you add 8

your answer is 10 8/9

66. change both fractions to a mixed number

9 5/9=86/9
8 1/6=49/6

multiply 86 and 9 by 2

86×2=172
9×2=18

multiply 49 and 6 by 3

49×3=147
6×3=18
now subtract :

172/18-147/18=25/18
divide 25 by 18

25÷18=1 (rounded whole number)
18×1=18
to get 25 you add 7

your answer is 1 7/18

hope this helped

Okay, so first off as you can see, 9 - 8 is 1, so now u have 1 5/9 - 1/6. Now u need to find a common factor between 9 and six, which is 18. Make 5/9 into 10/18 and 1/6 into 3/18. Now u have 1 10/18 - 3/18 which = 1 7/18
