5/9 = 60/108 factor out 12, top and bottom 12*5/12*9 eliminate 12; top and bottom 5/9 ------
12 x 9 - 13 = 95
5/12 +4/9 = 15/36 = 16/36 = 31/36
81/4+ 15/12= 8 + 1 + 1/4 + 5/12 = 9 + 3/12 + 5/12 = 9 + 8/12 = 92/3
3/4 + 5/6 = 9/12 + 10/12 = 19/12 = 17/12
5/9-1/3 is the same as 5/9-3/9. This would then subtract out to be 2/9. (2 over 9)
3/9 (three over nine)
12/5 ÷ 12/9 = 12/5 x 9/12 = 9/5 = 14/5

5/12 - 9/12 = -4/12
4/9 just subtract the numerators because the denominators are the same.
-9 = h/12 + 5 Multiply all terms by 12 to eliminate the fraction: -108 = h+60 Subtract 60 from both sides: -168 = h So: h = -168
12/11 = 108/99 10/9 = 110/99 10/9 - 12/11 = 2/99 12/11 - 10/9 = -2/99
get them to have the same demoninator. like if you have 5/6-3/4 make it 10/12-9/12. then just subtract.
5/12 is less than 9/12.
- 5m + 12 = - 9 subtract 12 from each side - 5m + 12 - 12 = - 9 - 12 - 5m = - 21 divide both sides integers by - 5 (- 5/- 5)m = - 21/- 5 m = 21/5 -----------------------check in original equation = 5(21/5) + 12 = - 9 - 105/5 + 12 = = 9 (now, 12 = 60/5 , so) - 105/5 + 60/5 = - 9 - 45/5 = - 9 - 9 = - 9 ----------------checks
