Rounding - Off Decimals
To round - off decimals, consider the digit on the tenths place. If the digit on the tenths place is 4 and below, retain the digit on the ones place. If the digit on the tenths place is 5 and above, add 1 to the digit on the ones place. It is simply rounding - off the decimal to the nearest whole number. To further understand how it is done, consider the examples below.
