Rounding numbers to the nearest tens is not difficult at all. In fact, it is so simple that you do it and you don’t even realize it.
Simply put, when you have a number and you want to round to the nearest tens, this means that you will need to find which 10 they are nearest to. For example, if you think about the number 53, you can easily say that it is near 50 than it is near 60. And the same happens when you think of the number 88 and you can easily say that 88 is near 90 than it is near 80.
One of the things that you need to keep in mind when you are considering rounding numbers to the tens is that this is a very important math skill. After all, you can use it to know how much money you have but you don’t exactly know the number or when you have a general idea about how many items you have but you don’t know the exact number.
Besides, when you round to the nearest tens, numbers are also easier to work with. After all, instead of summing 68 and 49, it’s a lot easier to sum 70 and 50 and get an approximate value.
How To Round To The Nearest Tens – The Rules
The reality is that the rules that you need to follow when you are rounding a number to the nearest tens are very easy to understand and to follow.
All you need to know id that if the number is one, two, three, or four, round down. If the number is five to nine, round up.
If you need to round the number seven, seven is larger than five, so it rounds up to 10. If you need to round the number two, two is smaller than five, so it rounds down to zero.
