How do you round need help with homework?

Answer 1

First you have to know what your rounding to. A common example is rounding to a whole number. So if I were to round 4.3 to the nearest whole number, I would see that this number is in between 4 and 5 and those are the two nearest whole numbers.

In this case, it is closer to 4.0, so I would round down to 4. If I was told to round up and not just round, I would go up to 5.0 or 5.

You can also round to the nearest 10, 100, 1000 and so on. And on the other side of the decimal point you could round to the nearest 10th (the first number to the right of the decimal), 100th (the second number) and so on.
