726/1000 or 0.726.Rounding is more easily performed on decimal numbers rather than fractions.When rounding consider the portion of the number that is less than the value to which the number is to be rounded.In this example, rounding is to be done to the nearest hundredth - so the portion of the number to be considered is 0.006.If 0.006 is nearer to the hundredth above - then round up.If 0.006 is nearer to the hundredth below - then round down.0.006 is nearer to the hundredth above so 0.72(6) is rounded up to 0.73 or 730/1000.
To add 0.889, 0.32, and 0.0033, you simply add the numbers together: 0.889 + 0.32 + 0.0033 = 1.2123. Rounding to the nearest hundred would mean rounding to two decimal places, so the result would be 1.21.
