Answer 1

11.55
if rounded to one decimal place it would be 11.6
and if to two decimal places it would be 12

Answer 2

I tried 11.6, let me try 12

Answer 3

As sheg said, it depends how many decimal places you want to end up with. When you round, you round the digit up if the following digit is equal to or greater than 5, and down otherwise.

Answer 4

Express your answer using two significant figures.
=11.55

Very close. Check the rounding and number of significant figures in your final answer.

Answer 5

Oh, two significant figures. Then it's 12.

Answer 6

how do you know it's 2 !!

Answer 7

Because 11.55 to two significant figures is 12.

Answer 8

oh sryyyyyy it's already saying that, I'm so tired didn;t read carefully

Answer 9

so whenever we get 5 we round it up ?!

Answer 10

yes

Answer 11

if it is higher than five
like 11.57 rounding off will be 11.6

Answer 12

omg the 12 is wrong too

Answer 13

as 11.6 is having after decimal 6 greater than 5 so rounded off to 12

Answer 14

Yes, if rounding is required. But significant figures is slightly different. Rounding to 3 decimal places means you end up with 3 figures after the decimal. Three significant figures means there are a total of three significant figures, regardless of the position of the decimal place.
Eg.
12.1
135
0.154
Are all three significant figures.

Answer 15

let me try and explain 11.55 so what you do is you start from the last number which is 11.55 now we round it up because it is 5 so it will turn to 11.6 if we still want to round that up then 6 will get rounded up because it is bigger then 4 so it will turn to 12

Remember anything that is above 4 should get rounded up e.g. 5,6,7,8,9
anything that is 4 and below will get rounded down e.g. 4,3,2,1

Answer 16

hey is ur question how many significant digits are in 11.55??

Answer 17

Because if that's the question, then it's 4 =)

Answer 18

Answer 19

I'm getting crazy I tried everythings but it doesn't work ... 11.4 11.40 11.5 11.6 11.60 11.70 none of these worked

Answer 20

What's the EXACT question, verbatim? What sheg is saying is that if it's asking for how many significant figures are in 11.55, then the answer is 4 (not 11.4, just 4).

Answer 24

Answer 27

Try 12. As "12." including the .

Answer 28

what is that !

Answer 29

12.

If you put a decimal place in it indicates an exact number of significant figures. 12. means two significant figures, regardless of how else it is rounded.

Answer 30

I know it sounds silly if you're not familiar with significant figures, but it is true =)

Answer 31

I'm canfuse, I tried 12

Answer 32

12. is different to just 12 when talking about significant figures.

Answer 33

that's stuped the answer was 11, but thank you guys ... if you see 11.55, you have to round it to 11, when you see 5 you have to round it down not up

Answer 34

What?! That is is absolutely ridiculous, never would 11.55 be rounded down to 11.

Answer 35

well when i was in school they did say you can do either but i've always stuck to rounding up so i can see why it accepted 11
