Question

If the weight of five sheets of paper is 20g,how many sheets of the same paper would weigh 2.5kg?.Answer with process.

Answer 1

2.5 kg=2500g
Weight of one sheet=20/5=4g
So no of sheets= 2500/4
=625 sheets

Answer 2

Solution:
Here given weight of five papers
hence, let the weight of one paper be x ● 5x = 20g
● x = 20/5g
● x = 4 g
thus, weigh of 1 paper is 4 g.
Now, 1kg = 1000 g
hence, 2.5 kg = 2500 g
total weight of paper
total no. of papers = _______________
weigh of 1 paper
2500g
total no. of papers = ______
4 g
total no. of papers = 625
hence total papers are 625 whose wight is 2.5 kg .
