A bundle of paper has a height of cm. If all the papers were of equal thickness and the thickness of each paper was mm, how many papers are there?
First make the units the same. There are mm in cm, so multiply the number of centimetre by 10 to convert to millimetre.
To find the number of papers, divide the height of the bundle by the thickness of each paper. We can change the divisor into a whole number by multiplying the divisor and dividend by .
So, there are 50 papers.
