Answer:

750 sheets

Step-by-step explanation:

2.5 kilograms=2.5*1000=2500 grams

2500/40=62.5 stacks-of-12-papers

62.5*12=750 sheets of paper

To check our work:

Let's set x as the weight of one sheet of paper.

12x=40 grams, x= 3 1/3 (three and one thirds) grams

3 and 1/3 *750= 2500 grams

2500 grams=2.5 kilograms
