To round a number, the decimal place that you want to round to, needs to be specified. If you want to round to the tenths place or to 1 decimal place, then this number is already there: 7.7 is seven and seven tenths. If you want to round it to zero decimal places, or to the nearest whole number, then look at the tenths place and if it is 0-4 you round down to 7, if it is 5-9 (which it is) you round up to 8.
11.3 rounded to one decimal place is 11.3. "To one decimal place" simply means that your number should only have one decimal number in it. When you round, numbers 1 to 4 round down (so 11.32 would become 11.3) and numbers 5 to 9 round up (so 11.38 would become 11.4).
As I would explain and show students, in order to round, you look at the number in the place to the right of where you want to round. If that number is 5 or more, you round up. If it's less than 5, you round down.For example, you want to round 12.54 to 1 decimal place. Look at the number in the second decimal place. That number is a 4, which is less than 5. So you'd round this down. That means your answer would be 12.5.But what if the original number was 12.58 and you needed to round this to 1 decimal place. The number in the second decimal place is an 8, which is greater than 5. So you'd round up. That means taking the number in the first decimal place and increasing it by one. So you'd round to 12.6.
The answer is 4.4 Drop the 6 and increase the 3 to 4
125.4 Taking a look at the number 125.3546 and wanting to round to the 1st decimal place you would take a look at the second decimal number (5) and see that it is greater than 5 so the 3 on 125.3 would round up to 4 to get the answer of 125.4

The 2nd decimal place is a 4, so round down: → 0.0471 to 1 dp is 0.0
It is: .4110 rounded to 4 decimal places
7.446 is rounded to 7.45. Look at the number to the right of the second decimal place (or the hundredth place), if: x>= 5 then round up, x<5 then round down. Since 6 is >= 5 we round 4 up to 5.
Look at the digit at the far right, if it's 4 or less, round down. If it's 5 or more, round up. Therefore, 0.00045 rounded to the nearest decimal place would be 0.0005.

1.83 is 1.8 when rounded to one decimal place. The reason for this is the rule of thumb where 1 to 4 you round down, 5 to 9 you round up, in your case it's 3, thus you round down.
look to the place next to it on the right and if its 4 through 0 round down and if its 5 though 10 round up

You would round it up... to read 4.0 (or simply 4).
