What is the least common multiple for 20 and 36?
The LCM of 20, 36, and 45 is 180. We look at the largest number, 45. For it to be a multiple of 20, it must end with a zero and have an even second-last digit. To get 45 to end with a zero, we can multiply it by 2, which gives us 90. 90 does not have an even second-last digit, so once again we multiply it by another 2, which gives us 180. 180 ends with a 0, and has an even second-last digit. If you then attempt to divide 180 by 20, 36 and 45, you'll find that it divides perfectly into all 3.

How long is a school year in america?
School years generally have to be 180 days long (not counting weekends or holidays...students must just attend 180 schooldays in one year, but school years actually last longer than 180 days since there are weekends and we have a few breaks during the year as well). Most schools will start sometime between mid August and early September, and end between late May and mid June. So the school year usually ends up lasting just a little over 9 months. And then we get about 2 1/2 months off for summer break in between school years.
