This is 3.9 when rounded to one dp. Go to the second digit after the decimal place, if this is 5 or more than increase the first decimal place, if it's less than five as in this case, leave the first decimal place as it is.
round 0.2975 to 1 decimal place = 0.3
to round 68.4 to one decimal place = 68.4
Round to the nearest tenth, the first decimal place to the right of the decimal point.
To one decimal place it is 4.1
It represents the tenths place.
The second decimal place is 5 or more, so the first decimal place increases by 1.69.6
First, determine what number is in the second decimal place. As it is a five in this case, the first decimal place is rounded up with the answer becoming 3.5.
If you want to round to the first decimal place, look at the second decimal place.If that's 5 or more, add '1' to the first decimal place, and discard the rest.If it's less than 5, keep the first decimal place as it is, and discard the rest.2.543 rounded to the nearest tenth is 2.5 .
nearest tenth is first place after the decimal. Look to the second place after the decimal; if it is less than 5 you keep the original first place after the decimal; if grater than 5, you round up by adding 1 to the irst place after the decimal; in your case since the second place after decimal is 0 then the nearest tenth is 3.0
3.1You look at the second digit after the decimal point and ask if it is greater than or equal to 5.If it is you round up the first digit after the decimal point. If not, then you round down (i.e. the first digit after the decimal point stays as it was).So for 3.077, "7" is greater than or equal to five so we round up to 3.1 (to one decimal place).
To round to 1 decimal place you'll have to look at the decimal place after it (the hundredths place). In this case, 8 is in the tenths place (first decimal place) so we look at the hundredths (or second) decimal place, which is 6. If the second number is 0-4, you do not round the first decimal place up. Ex. rounding 1.232 to the tenths place would be 1.2. If the second number is 5-9, you round the first decimal place up. Ex. rounding 1.252 to the tenths place would be 1.3. Here we see that our second number is 6, which is between 5 and 9, so we round up- 9.865 round to 9.9. There are a few technicalities with the thousandths place rounding up the hundredths place, which can in turn round up the tenths place, but for the purposes of this question specifically that doesn't really matter.
0.8To round to 1 decimal place we look at the second digit after the decimal point and ask if it is equal to or greater than 5. If it is we round the first digit up (add 1 to it). If not we round down (the first digit remains the same).Here the second digit is "6" and so we round the first digit up to "8".
round 0.2975 to 1 decimal place = 0.3
to round 68.4 to one decimal place = 68.4
This is 3.9 when rounded to one dp. Go to the second digit after the decimal place, if this is 5 or more than increase the first decimal place, if it's less than five as in this case, leave the first decimal place as it is.
