1217/18+42/3... First - deal with the whole numbers... 12+4=16.
Next make both fractions have the same denominator. Since they're both factors of 18, make them both over 18, so you get 17/18+12/18. This equals 29/19 or 111/18 - now - add the original 16 (from the first bit) and your grand total is 1711/18
17/3 minus 15/4 is 1 11/12
45/12 − 17/12 = 25/6
52/3 - (-3/4) = 17/3 + 3/4 = 68/12 + 9/12 = 77/12 = 65/12.
-3/4 − 5/6 = -19/12 or -17/12
17
17/3 minus 15/4 is 1 11/12
4 and 17/18
It is -25/36
-17 1/3
45/12 − 17/12 = 25/6
It is: 5/9 - 1/12 = 17/36
17/18 minus 2/3 is 5/18
52/3 - (-3/4) = 17/3 + 3/4 = 68/12 + 9/12 = 77/12 = 65/12.
17/18 - 2/3 = 17/18 - 12/18 = 5/18
12 minus -5 is 17.
8.66-3.86=4.8=4 wholes and 17 over 21
17 1/3 - 5 2/3 = 11 2/3 or eleven and two thirds.
