Here’s how to round any decimal to the nearest hundredth.
Let’s take 3.52 for example. Keep in mind that if the (hundredth) number is 4 or less, then the whole number is rounds down one. If it is 5 or more, it rounds up one.
2 is in the hundredth place, and it is 4 or less. That means that the whole number (3) rounds down one. This means that 3.52 rounds to 2.
Apologies if this is still confusing, I tried the best to explain. If this helped, you’re welcome!
