Answer :
Final answer:
To find the number of pieces of paper in the stack, divide the thickness of the stack by the thickness of each individual piece of paper. In this case, the stack measures 0.9 centimeters thick and each piece of paper is 0.01 centimeter thick. Therefore, there are 90 pieces of paper in the stack.
Explanation:
To find the number of pieces of paper in the stack, we need to divide the thickness of the stack by the thickness of each individual piece of paper.
Given that the stack of paper measures 0.9 centimeters thick and each piece of paper is 0.01 centimeter thick, we can use the formula:
Number of pieces of paper = Thickness of stack / Thickness of each piece of paper
Number of pieces of paper = 0.9 cm / 0.01 cm = 90 pieces of paper
