Resuelve las siguientes operaciones
3/4 + 1/12 - 1/6 = 9/12+1/12-2/12= 9+1-2/12=8/12 = 2/3
Nota simplificas 8/12 = primero en 2 saldrá 4/6 y luego en 2 dará resultado en 2/3
4/6 - 1/3 + 2/5= 2/3 - 1/3 + 2/5 = 1+3 +2/5 = 5/15+6/15 = 5 + 6 / 15 = 11/15
3/8 + 2/5 + 1/6 = 45/120 + 48/120 + 20/120 = 48 + 45+ 20/120 = 113/120
6/8 - 7/4 + 1/12 = 3/4 - 7/4 + 1/12 = -1 + 1/2 = -1 * 12 + 1 /12 = -11/12
3/5 - 7/4 + 1/12 = 36/60 - 105/60 + 5/60 = 36 - 105 + 5/ 60 = -64/60 = -16/15
6/7 + 1/4 - 1/2 = 24/28 + 7/28 - 14/28 = 24+7-14/28 =17/28
