Explicación paso a paso:
4/11+3/12= 12.4 / 132 + 3.11 / 132 = 48/132 + 33/132 = 81/132 = 27 / 44
18/24+3/15 =18.5 /120 + 8.3 / 120 = 90/120 + 24/120 = 114/120
23/45-5/63= 23.7 /315 5.5 / 315 = 161 / 315 - 25/ 315 = 136/315
4/48+3/12= 4/48 + 3.4/48 = 4/48 + 12/48 = 16/48 = 1/3
10/30+3/3 = 10/30 + 3.10/30 = 10/30 + 30/30 = 40/30. = 4/3
5/10-20/55= 5. 11 /110 - 20. 2 / 110 = 55/110 - 40/110 = 15/110 = 3/22
12/100+25/35=12.7 /700 + 25.20/700= 84/700 + 500/700= 584/700
12/7-35/25= 12.25 / 175 - 35.7/175 = 300/175 - 245/175 = 55/175 = 11/ 35
48/78-12/30= 48.5/ 390 - 12.13/390 = 240/390 - 156/390= 84/390
6/16+8/35= 6.35 /560+ 8.16/ 560 = (210 + 128 ) / 560 = 338/560
8/135-4/76= (8.76)/(135.76) - ( 4.135)/(135.76) = (608 + 540)/10260= 1148/10260
10/5-4/75= 10.15 /75 - 4/75 = 150/75 - 4/75 = 146/75
