P.S its for a science report thing not a maths thing so yerh its not homework its simply a silly essay that im stuck with rounding

lol thnkz! PEACE OUT! mwah

Answer 1

The whole number is the number to the left of the decimal. Look at the first digit to the right of the decimal. If it is less than five, delete everything to the right of the decimal and leave the whole number alone. If it is five or more, delete everything to the right of the decimal and raise the whole number by one.

Example: 7.475

7 is the whole number
4 is the first digit to the right
4 is less than 5
delete the 475 and leave the 7 alone
the answer is 7

11.615
11 is the whole number
6 is the first digit to the right
6 is greater than 5
delete the 615 and add one to 11
the answer is 12

The rest should be easy to do following these steps.

Answer 2

Lets start with the first one. The 7.475 expressed as a whole number is 7 or 8, which oen is the most correct?.

You find the error by subtracting the original from the whole number you round to and disregard the sign of the answer.

Lets try 7 for 7.475, then we are in error by 0.475

Lets try 8 for 7.475, then we are in error by 0.525

Which is the smallest error? the 0.475 so we are making a smaller error by choosing to round to 7

All the other numbers in your list can be treated the same way and after you do a few of them you can develop a rule of thumb for rounding to whole numbers. If the bit after the decimal point is less than 0.5 round down, if greater than 0.5 round up. There is a special case that if the bit after the decimal point is equal to 0.5 then we round up by convention.

by inspection you wlll see if you use the rule of thumb:

7.475 ~~ 7
59.004 ~~ 59
51.529 ~~ 52
20.622 ~~ 21
11.615 ~~ 12

I do not know where you got your numbers but please note that you do not round till the very end, that is do not round up intermediate results.

So if you are to give the answer to 7.475 + 59.004 + 51.529 + 20.622 + 11.615 to a whole number you would not add up
7 + 59 + 52 + 21 + 12.

Example:

7.475 + 59.004 + 51.529 + 20.622 + 11.615 = 150.245 ~~ 150

7 + 59 + 52 + 21 + 12 = 151

We all know 150 does not = 151

Hope this helps,

Answer 3

You just look at the digit immediately after the decimal point; that is, the tenths digit. If it is 0, 1, 2, 3, or 4, round down. If it is 5, 6, 7, 8, or 9, round up. When you round, you look at the whole number portion, which is what comes before the decimal point. If you're rounding down, you just keep the whole number as it is; you round down by eliminating the decimal portion. If you're rounding up, you need to increase the whole number by one.

7.475 has a 4 in the tenths place, so we round down: 7.

51.529 has a 5 in the tenths place, so we round up: 52.

Answer 4

Actually, rounding off 7.475, 59.004, 51.529, 20.622, 11.615 is not really a hard thing to do. You just simply observe the numbers next to the whole number you are needed to work with. The simple rule is this, if the number next to your significant digit, is less than five like the number you sent 59.004 and 7.475; You just simply drop those number or ignore like a zero next to your whole number, that is, only if you are required to round it off to whole numbers. And that should be, 59.0 or simply 59 and 7.0 or 7 itself. And if the number or decimal numbers next to to your ones digit is greater that five(5), the number should add one to ones digit; eg. 51.529 will become 52.0 or simply 52 and 20.622 will become 21.0 or simply 21, and 11.615 will be 12.0 or just simply 12.


The only restriction is that you only add one next to the place value that are require to be rounded off if the number next to it is five or greater that five(5); And retained if and only if the number that is/are subject for rounding off iss less than five.

eg. Round the following numbers into nearest hundredths:

56.0036 that is 56.0,the number in the thousandths and tenthousandths place are ommited

59.2957 that is 59.30, one is added to nine-hundredths because the number next to it is greater than five.


21.0998 that is 21.10, same reason as 59.2957.


Take note that you should know the place value you are needed to work with..


Hope it helps!Goodluck!!
