Ceramic tiles measure 2in by 3in. What is the LEAST number of tiles that are needed to completely cover a square area that is 2ft on each side?

To be a multiple of 5 all you need to do is see if the last digit is 0 or 5. Since there are 10 choices for the last digit the probability is 2/10 or 1/5. And divisible by 2 means the last digit is 2,4,6,8,or 0, so in a similar way the probability is 5/10 or 1/2





2 feet is 24 inches. So see how many times 2 goes into 24, then how many times 3 goes into 24, then multiply the answers.
