Question

if the thickness of 500 sheets of paper is 4.5 cm what would be the thickness of 360 such sheets​

Answer 1

Thickness of 360 sheets is 3.24 cm

Solution:

Given that,

The thickness of 500 sheets of paper is 4.5 cm

To find:  thickness of 360 such sheets​

Find the thickness of one sheet

$\text{Thickness of one sheet} = \frac{4.5}{500}\\\\\text{Thickness of one sheet} =0.009$

Find the thickness of 360 sheets

$\text{Thickness of 360 sheets} = \text{Thickness of 1 sheet} \times 360\\\\\text{Thickness of 360 sheets} = 0.009 \times 360\\\\\text{Thickness of 360 sheets} = 3.24$

Thus thickness of 360 sheets is 3.24 cm

Answer 2

The thickness of 360 sheets is 3.24 cm.

Step-by-step explanation:

1. When numbers of sheet increase , thickness will also increase. Similarly when numbers of sheet decrease , thickness will also decrease.

  It is case of direct proportional case.

2.

  Thickness of sheet(cm) :-             4.5                      x

 

  Number of sheet :-                       500                     360

3. From

       $\mathbf{\frac{x}{360}=\frac{4.5}{500}}$

       So

      $\mathbf{x=\frac{4.5}{500}\times 360}$

      $\mathbf{x=3.24 \ cm=}$This is thickness of 360 sheets.
