Explicación paso a paso:

Primera:

Fila 1 : (20 - 15)x6 = 5x6 = 30

Fila 2: (15 - 7)x6 = 8x6 = 48

Fila 3: (12 - 1)x6 = 11x6 = 66 = x <---------------Respuesta

Segunda:

Fila 1 : (20 + 30)/5 = 50/5 = 10

Fila 2: (12 + 28)/5 = 40/5 = 8

Fila 3: (14 + 66)/5 = 80/5 = 16 = x <------------- Respuesta

Tercera:

Fila 1 : (32/8)(10) = 4(10) = 40

Fila 2: (45/5)(10) = 9(10) = 90

Fila 3: (144/12)(10) = 12(10) = 120 = x <---------------- Respuesta
