alekssr [168]

Answer:

14.88 resmas

Step-by-step explanation:

Los maestros de una escuela planean enviar 6 boletines al año a cada una de las 620 familias con estudiantes en la escuela.

Esto significa: El número total de boletines que recibe cada familia = 6 × 620 familias

= La escuela envía 3720 boletines cada año

Cada uno de los boletines necesita 2 hojas de papel.

1 boletín = 2 hojas de papel

3720 boletines =

Cruz multiplicar

3720 boletines × 2 hojas

= Se necesitan 7440 hojas de papel en un año

El papel se vende en resmas de 500 hojas.

¿Cuál es la cantidad mínima de resmas de papel necesarias para imprimir los boletines escolares en un año?

500 hojas de papel = 1 resma

7440 hojas de papel = y

500 × y = 7440 × 1

y = 7440/500

y = 14.88 resmas

La cantidad mínima de resmas de papel necesarias para imprimir los boletines escolares en un año es 1488 resmas
