Well, isn't that a happy little question! If you're trying to figure out how many tens fit into 300, you simply divide 300 by 10. And when you do that, you'll find that 30 tens fit perfectly into 300. Just like painting a beautiful landscape, math can be a joy when you take it one step at a time.
Oh, dude, let me grab my calculator for this intense math problem... Okay, so 300 divided by 10 is 30. So, like, there are 30 tens in 300. Math is wild, man.
