How to correct something to nearest second? e. g 12.360

12.000

Step-by-step explanation:

when rounding to the nearest second you have to look at the numbers that come after the decimal to decide whether to round up or down

if the tenths column is 5 or more round up, if it's less than 5 round down

12.360

look at the tenths column which is 3. It is less than 5 so the number 2 in 12.360 stays the same, and the numbers after the decimals are removed and replaced with 0

final answer : 12.000

if you wanted to correct 12.680 to the nearest second look at the 6 which is in the tenths column. It is 5 or more so the number 2 in 12.680 rounds up to 3 and the numbers after the decimals are replaced with 0

it is rounded to 13.000
