Explicación

Encontraste el sumatorio correcto al hallar el mínimo común múltiplo (20) y simplificar.

Con denominadores 24 obtienes 9/24+8/24+10/24+7/24 = 34/24 = 17/12.

Con lcm 60 conviertes cada fracción y sumas: 40+48+10+45 = 143.

Con lcm 126: 70+36+27+7 = 140/126 = 10/9.

Con denom 30: 15+10+6+5 = 36 → 36/30 = 6/5.

Con denom 12: 9+8+10+1 = 28 → 28/12 = 7/3.

Con denom 150: 105+20+50+27 = 202 → 202/150 = 101/75.

Con denom 126: 72+70+27+77 = 246 → 246/126 = 41/21.

Con denom 40: 16+14+15+9 = 54 → 54/40 = 27/20.

Con lcm 990: 110+180+120+50 = 460 → 460/990 = 46/99.
