Rounding Decimals
Rounding off a decimal is a technique used to estimate or approximate values. Rounding is most commonly used to limit the amount of decimal places. Instead of having a long string of decimals places, or even one that goes on forever, we can approximate the value of the decimal to a specified decimal place. We round decimals to get an estimate of a whole number.

__**What Does Rounding Decimals Look Like?**__ Example 1: Round 0.1284 to 2 decimal places. Solution: The 3rd decimal number, 8, is bigger than 4, so we add 1 to the 2nd decimal number 2, and drop the rest of the decimal numbers. Our answer is 0.13.

 * __How Do We Round Decimals?__**
 * 1) Find the place value you want (the "rounding digit") and look at the digit just to the right of it.
 * 2) If that digit is less than 5, do not change the rounding digit but drop all digits to the right of it.
 * 3) If that digit is greater than or equal to five, add one to the rounding digit and drop all digits to the right of it.
