0.889 + 0.32 + 0.0033 = 1.2123 Rounding that to the nearest hundred is zero. Rounding that to the nearest hundredth is 1.21
There is no universal "better". Rounding off is a trade-off between reducing the accuracy and simplifying calculations. Also, if there are other numbers in an addition that are rounded to the nearest hundred, there is no point in rounding your number to the nearest ten.
rounding this question to the nearest hundred, the answer is 0 rounding this question to the nearest ten, the answer is 40 the most specific i can get this answer is aproximately 37.0O0O0O0O0O0O0O0O0O0
332 + 168 = 500 which does not need rounding.
157.93 plus 104.52 = 262.45Rounding to the nearest hundred this becomes 300. Rounding to the nearest ten this becomes 260.In this instance rounding to the nearest ten is more reasonable.
45 + 39 = 84, so if you want to round to the nearest ten, that's 80, or nearest hundred is 100. Otherwise, it doesn't turn out to a decimal, so it doesn't need rounding to the nearest one.
8 + 6 = 14
It is 500.00
Rounding both numbers to the nearest ten it is about 80
23.15 + 45.78 = 68.93 That is already at the nearest hundredth, so it does not need any further rounding.
