Question

IF the mass of 35 sheets of paper is 280g, how many sheets will weigh 7.2 kg?

Answer 1

mass of 35 sheets of paper is 280g
so that mass of 1 sheet of paper is 8g
therefore, sheets of paper which mass is 7.2kg
=7.2*1000/8
=900 sheets Ans

Answer 2

7.2 kg is the mass of 900 sheets.

Given : Mass of 35 sheets is 280g.

To find : Number of sheets that will have a mass of 7.2 kg

Solution :

We can simply solve this mathematical problem by using the following mathematical process. (our goal is to calculate the number of sheets)

Here, we will be using the normal arithmetic method.

So,

280g is the mass of = 35 sheets

1g is the mass of = 35/280 sheets

1000g is the mass of = (35×1000)/280 sheets

1kg is the mass of = (35×1000)/280 sheets (As 1 kg = 1000g)

7.2kg is the mass of = (35×1000×7.2)/280 = 900 sheets

(This will be considered as the final result.)

Hence, 7.2 kg is the mass of 900 sheets.
