What is the greatest odd number less then 250 explain how you know

The greatest odd number that is less than 250 is 249. The '9' at the end makes it odd and it is as big as you can get without going over 250.

I think it might take 4/6, or 2/3

Explanation: because 1/2 a can of sauce covers 3/4 of the pizza, you still need 1/4 of the pizza covered. 1/4 if 1/3 of 3/4. That means you need an additional 1/3 of the 1/2 can of sauce - 1/3 of 1/2 is 1/6. So, if we add the original 1/2, which is equal to 3/6, with the additional 1/6, we get 4/6. 4/6 can be simplified to 2/3. I’m not sure if I’m right cause I’m bad at math but you could give it a try. :)
