Thickness of 12 sheets of paper is 2.4mm. find the thickness of 1 sheet of paper.

Divide.

2.4/12 = ?

To find the thickness of a single sheet of paper, we can divide the total thickness of 12 sheets by the number of sheets.

Given that the thickness of 12 sheets is 2.4 mm, we can set up the following equation:

Total thickness of 12 sheets / Number of sheets = Thickness of 1 sheet

2.4 mm / 12 sheets = Thickness of 1 sheet

Simplifying the equation:

0.2 mm = Thickness of 1 sheet

Therefore, the thickness of a single sheet of paper is 0.2 mm.
