Para resolver la operación \( 8,55 : 2,5 \), primero podemos simplificar dividiendo ambos números por 2,5. Así que transformamos el 2,5 en 25 mediante el movimiento decimal: \( 8,55 : 2,5 = 8,55 : \frac{25}{10} = 8,55 \times \frac{10}{25} = \frac{8,55 \times 10}{25} = \frac{85,5}{25} = 3,42 \). La respuesta es (B) 3,42. Ahora, un consejo común es asegurarse de ajustar el número de decimales antes de realizar la operación. Muchos cometen el error de olvidar mover la coma decimal, lo que puede llevar a respuestas incorrectas. ¡Practicar con ejemplos ayuda a evitar esos tropiezos en el futuro!
