How do you round to the nearest second?

Hint: .5 = .50 = .500 = .5000

When rounding to the nearest second, you have to check the numbers that come after the decimal(5.89) to see if you should round up or down.

If the number in the tenths column is 5 or more (i.e. 4.5, 3.8, 4.9, 1.7, 2.6), you have to round up. If the number in the tenths column is less than 5(i.e. 1.2, 9.3, 7.4, 9.1, 2.0), you have to round down.

Ex:

57.28 = 57.00

Why? Because .28 is less than .5 and if the number in the tenths column is less than 5(i.e. 1.2, 9.3, 7.4, 9.1, 2.0), you have to round down.

Rounding up means that 1 more full second is added to the whole seconds and the numbers that come after the decimals removed.

Ex:

52.85 = 33.00 (=52.85 + 1 - .85)

Rounding down means that the whole seconds (the numbers before the decimal) stay the same, no whole seconds are added, and the numbers that come after the decimals removed.

Ex:

57.28=57.00 (=57.28 + 0 - .28)

Basically, you round to the nearest whole second based on these rules:

1. If the numbers that come after the decimal are .5/.50 or higher, you round up
2. if the numbers that come after the decimal are less that .5/.50, you round down

Ex:

57.28=57.00 because the numbers that come after the decimal are less than 0.50

.28<.50
