Question

a picnic blanket is 1 meter across.an ant is 1 centimeter in length.how many ants of the same length would fit end to end across the length of the picnic blanket

Answer 1

Since the prefix "centi" means hundredth, we can assume one ant is going to take up one hundredth of the length. Since multiplying anything by 1 (e.g. 2 * 1 = 2) equals that number, we can "multiply" 100 by 1 to get 100
