To round to the nearest tenth use the hundredth digit to decide to round up or down. The hundredths digit is a 7 so round up. The tenths digit is a 9, so adding 1 gives 10, which means keep the 0 in the tenths column and add 1 to the ones column: 30.97 → 31.0 to the nearest tenth Note that the .0 is normally not written, but as it is written it is significant: it shows the number is accurate to the nearest tenth.
To convert fromCelsiustoFahrenheit, multiply by 1.8 and add 32.47 * 1.8 = 85.6 (exact)85.6 + 32 = 117.6°F
The 7 interior angles of an heptagon add up to 900 degrees.
10.5 seconds. When you round off to the nearest tenth, look at the hundredth number. If it is less than 5 (exclusive of 5), just remove all the numbers from the hundredth digit. If it is at least 5, add 1 to the tenth digit, then remove all digits from the hundredth onwards.

8.2 8 is the ones column, 2 is the tenths, and 1 is the hundredths. If the hundredths are 5 or higher then rounding to the tenths you add one to the tenths place and drop the hundredths. Since 1 is less than 5 the nearest tenth is 8.2
To round to the nearest tenth, look at the hundredths digit: if it is 5 or more round up otherwise round down. For 95.25 the hundredths digit is 5, so round up: 95.25 → 95.3 to the nearest tenth.
39.05 and you want to round it to the nearest TENTH, then you write a 5 under the HUNDREDTH position. Then you write zeros under all the other digits to the left and also preserve the decimal point as shown below. 39.05 00.05 Add the two numbers to get 39.10 and truncate the number after the tenth's position to get 39.1 which is the answer. If the original number was 39.01 then you will have 39.01 00.05 and when added will give 39.06 and after truncation will give you 39.0 If the original number was 39.09 then you will have 39.09 00.05 and when added will give 39.14 and after truncation will give you 39.1
The answer is 2, because 0.6 is 0.4 more to 1 so I add 0.4 and it is rounded to 1, so it’s 2.
