10.
The way I remember it is..
"4 or below keep it down low, 5 or above give it a shove."
When the last digit of a significant digit is 5 and we need to round it, we follow a rule called "round half up". This means that we round the digit up to the nearest number if the digit before it is odd, and round down if it's even. For example, 2.5 would round up to 3, while 3.5 would also round up to 4.
To round millimeters to the nearest centimeter, divide the millimeters by 10 to convert them to centimeters. Then round the centimeter value to the nearest whole number. If the remainder after division is 5 or more, round up; if it's less than 5, round down.
5' 6" = 5 feet 6 inches5.51181102 feetSo, that would be 5'6" if you round it up.
To correct to 4 significant figures, you need to round the number to have four digits starting with the first non-zero digit from the left. If the fifth digit is 5 or more, round up the last remaining digit. If it's less than 5, keep the digit as it is.
You count the number 5 as the first significant figure,7 the second, 6 the third. You then round the it up or down from the following number. As it it 0 you round down, leaving it as 6. A: 5.76
5 or more round up
round up
7 will round up.
15 round 5 0-4 round down 5-9 round up
If I think your asking the question how I think your asking it, then any number 5 and above you round up. If its below 5 you round down. :-)
The usual practice with a 5 is to round up, so for example 7.5 is about 8.
For example:- If it is 4.1, 4.2 4.3 or 4.4 then we round it up to 4 or else if it is 4.5 ,4.6, 4.7, 4.8, 4.9 then we round it up to 5.
The tenth place in this case is the 2. You look at the number to the right of this which is a 5. If the number is 5 or above you round up if it is below 5 you round down. Since it is a 5 you would round 2 up to a 3. 0.3 is your answer(:
18.27 ( 5 and up round up 4 and down round down :P )
To the nearest 5, 4.3 rounds up to 5.
If the previous digit is 5 or more then round up but if the previous digit is less than 5 then round down.
Personally, I have always been taught to round up. (ex. if an answer is 0.5, I usually round it to 1.)
