The depends to what decimal place you are rounding the number.If you are rounding to hundredths, it will be 2.27If you are rounding to tenths, it will be 2.3If you are rounding to the nearest whole number, it will be 2.
You may be thinking of rounding (right of the decimal) or zero suppression (left of the decimal).
It is rounded to 2.5 or 3 to the nearest whole number.
If you are talking about whole numbers, then it is 889. If it is a decimal value, then there is no answer.
I am assuming the question means where in life is rounding used? Rounding to hundredths is used with Dollars and Cents. Rounding to whole numbers is used when expressing approximations and things that can not be cut like people in an elevator.
1, if you want to round it to the nearest whole number. For rounding it to the nearest tenth (one decimal place), the answer is 0.7. For rounding it to the nearest hundredth (two decimal places), the answer is 0.67. etc. When you round it to the nearest millionth (six decimal places), you'll no longer be rounding up, because the answer will be the same as what you started with: 0.666666.
In the decimal system, when rounding numbers you look at the digit to the right of the desired decimal place. If that digit is 5 or greater, you round up; if it's less than 5, you round down. For example, if rounding to the nearest whole number and you have 4.6, it would round up to 5, but if you have 4.4, it would round down to 4.

0.9 rounded to the nearest whole number = 1
It would be 50. In rounding up, we add one and truncate the digits after the decimal point. In rounding down, we just truncate the digits. http://en.wikipedia.org/wiki/Rounding#Common_method
79 over 35 is 79/35. 79/35 as a decimal is 2.25714285714. To convert a decimal to a percent, multiply by 100. 2.25714285714 * 100 = 225.714285714% Rounding to the nearest hundredth of a percent is 225.71. Rounding to the nearest tenth of a percent is 225.7. Rounding to the nearest whole number is 226.
When rounding 7.68 to the nearest whole number, the decimal part (0.68) is less than 0.5. Therefore, rounding down will result in 7. So, 7.68 rounded to the nearest whole number is 7.
