Answer :
Final answer:
To solve this, you first find the thickness of one paper by dividing 2.5 cm by 150. The result is approximately 0.0167 cm. Then, divide 6.5 cm by the thickness of one piece of paper, 0.0167 cm. The answer is approximately 390, so there are about 390 pieces of paper in a pile 6.5 cm thick.
Explanation:
This question is about ratios and proportions. The first step is to determine the thickness of one piece of paper. If a stack of 150 pieces is 2.5 cm thick, to get the thickness of one piece of paper, divide 2.5 by 150. This is approximately 0.0167 cm.
Then, to find out how many pieces of paper are in a pile that is 6.5 cm thick, divide 6.5 by the thickness of one piece of paper, 0.0167. The result you will get is approximately 390. So, there are 390 pieces of paper in a pile 6.5 cm thick. I hope this helps! Remember, in mathematics, it's always helpful to understand the concepts behind the calculations you're doing.
