When rounding to a specific place, take a look at the digit immediately to the right of the target. If that digit is 4 or less, zero everything to the right of the target out. If that digit is 5 through 9, increase the target by one and zero everything to the right of it out. If the target is a 9, increasing it will turn it to zero and increase the digit to the left of the target by one.
in whole numbers, if the last part of the number is five or above, it rounds to the next 0. e.g. 47 rounds to 50
In decimals, if you say round to the nearest tenth, you look at the hundredth point and round up. e.g. 47.57 rounds to 47.6
Also, If you say round to the nearest hundredth, look at the thousandth point and round up
eg 47.575 rounds to 47.58
and so on
If the number ends in 1 2 3 4 round down and round the number up if it ends 5 6 7 8 9 to get rounded to the nearest ten.
If the number ends in 1-49 inclusively round down and round the number up if ends with 50-100 inclusively.
For bigger numbers like 1000000 half then take away 1 to find the number to round down and the rest is rounded up.
e.g. Round 776758 to the nearest million.
1/2 of 1000000 is 500000 - 1 is 499999.
So if the number is less than 7499999 round if not round up.
Answer is 8000000.

Rounding numbers is easy because their are two rules to rounding numbers. 1) a </= 4 then a = 0 2) a >/= 5 then a = 10
There are no set rules about rounding numbers, so when rounding numbers, mathematical rules about rounding can be used. For example, 14 would be rounded to 10, but 15 would be rounded to 20. For another example, 1144 is rounded to 1140 and 1145 is rounded to 1150.
The answer to an addition question should have no more decimal places than the smallest number of decimal places in the numbers being added. When rounding numbers, numbers 5 though 9 will be rounded up and 1 through 4 will be rounded down.
the purpose of rounding numbers is that you can get closer to the actual answer
rounding whole numbers and decimals
It depends on the degree of rounding.
The name comes from the way you round. Front end rounding is keeping the first number and rounding all the numbers after that.
Is the rounding is skidding
It is - if you use appropriate rounding. Rounding does not have to be to whole numbers.
rounding numbers is to nearest ten or hundred and compatible numbers are when you can do nearest 5
