Rounding has a simple rule. 5 or above? Up you shove. 4 or below? Keep it low.
1. What are you using to round?
56<u>2</u>0 : The tens place is the number we are either going to be rounding up or keeping. In this case, it is the 2 in 5620.
562<em>0 </em>: When rounding to the nearest ten, you look at the ones section. In this case, it is the 0 in 5620.
2. Execution
When rounding up to tens, look at the ones value. If the number is 5 or above, round the tens place up a number. (ex. 562<u>5</u> --> 563<u>0</u>) If the number is a 4 or below, keep the tens value the same. (ex. 562<u>4</u> --> 562<u>0</u>)
Since the ones place in 5620 is below a four, we are going to keep the tens value the same, so the answer is going to be 5620.
