What is the largest multiple of 37 which is less than 800?
I want to find the largest multiple of 37 that is less than 800, so I will start by dividing 800 by 37 and see what I get. I can use long division or a calculator to find that 800 divided by 37 is about 21.6. This means that 21 times 37 is the largest multiple of 37 that is less than 800, because if I multiply 37 by a larger number, I will get something bigger than 800. To find 21 times 37, I can use the distributive property and write 21 as 20 plus 1. Then I have 21 times 37 is the same as 20 times 37 plus 1 times 37. I know that 20 times 37 is 740, and 1 times 37 is 37, so 21 times 37 is 740 plus 37, which is 777. Therefore, the largest multiple so 37 that is less than 800 is 777.
