It is 11.4.
To round to 1 decmal place you need to get rid of the digit in the second decimal place.
If that digit is 0, you just drop it.
If it is 1-4 then you also drop it.
If it is 6-9 then you drop it BUT increase the previous digit by 1.
If it is 5 ...
Now here is a problem. If you always drop the 5 you introduce a downward bias. If you always increase the previous digit, you introduce an upward bias. So, with a 5, you need to round down half of the time and round up half the time so as to avoid a bias. A statistically sound solution is to round up or down so that the previous digit is even.
3.3 rounded to 1 decimal place is 3.0.
Go to the second decimal place; if it is less than 5; round down. If it is 5 or greater, round up. So, 1.51 rounded to 1 decimal place is 1.5.
To one decimal place it is rounded to 0.9
Well, isn't that a happy little question! When we round 6.45 to 1 decimal place, we look at the digit in the second decimal place, which is 5. Since 5 is 5 or greater, we round up the first decimal place to 6. So, 6.45 rounded to 1 decimal place is 6.5.
It is 8.8
round 0.2975 to 1 decimal place = 0.3
Oh, dude, it's like super easy. So, to round 2.73 to 1 decimal place, you just look at the number right after the decimal point. If it's 5 or greater, you round the number up. In this case, 2.73 becomes 2.7 because 3 is less than 5. Easy peasy, lemon squeezy!
It is then 31.2 when rounded to 1 decimal place
6.5- you round it until it has one decimal.
4.96432 rounded to 1 decimal place is 5.0.
It is 4.1 when rounded to 1 decimal place
3.3 rounded to 1 decimal place is 3.0.
Go to the second decimal place; if it is less than 5; round down. If it is 5 or greater, round up. So, 1.51 rounded to 1 decimal place is 1.5.
To round 4.21 to 1 decimal place, you look at the digit in the second decimal place, which is 1. Since 1 is less than 5, you keep the digit in the first decimal place the same, which is 2. Therefore, rounding 4.21 to 1 decimal place gives you 4.2.
6.32 rounded to 1 decimal place = 6.3
because
334.4 is already in 1 decimal place
