Oh, dude, you're hitting me with the tough math questions, huh? Alright, so 2 and a half is the same as 2.5, right? And since each whole number is divided into 10 tenths, there are 25 tenths in 2 and a half. But hey, who's counting, right?
Well, isn't that just a happy little question! In 2 and a half, there are 25 tenths. You see, each whole number is made up of 10 tenths, so when we have 2 whole numbers and a half, we have 20 tenths from the wholes and 5 tenths from the half. Happy counting!
