I can't answer for a specific conversion since you haven't given me any values, but as for the rounding part...
Sometimes it is advantageous to express a value in round numbers. To round to a particular place, look at the digit immediately to the right of the one you want to round to, in this case, the hundredths place. If that digit is 4, 3, 2, 1 or 0, zero it and everything to the right of it out. If that digit is 5, 6, 7, 8 or 9, increase your target digit by one and zero everything to the right of it out. If your target digit is 9, it will become a zero and increase the digit to the left of it by one.
The nearest tenth of 1%. Here you have to translate 1% into a decimal #. You will have to convert 1% into 0.01. Therefore, 0.01 will round down to 0.0.
To the nearest tenth.... 7.7
It is 6.9 to the nearest tenth
7.19 to the nearest tenth = 7.2
It is .9 rounded to the nearest tenth
90 degrees F
tan-1(0.8) = 38.65980825 degrees or 38.7 degrees to the nearest tenth.
43 degrees Celsius is equal to 109.4 degrees Fahrenheit when rounded to the nearest tenth.
As an integer, it is already rounded to the nearest tenth.
7
43 degrees Celsius is equal to 109.4 degrees Fahrenheit when rounded to the nearest tenth place.
900/7 = 128.6 degrees rounded 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
1.4 miles.
.3 miles
The nearest tenth of 1%. Here you have to translate 1% into a decimal #. You will have to convert 1% into 0.01. Therefore, 0.01 will round down to 0.0.
5895 to the nearest tenth is just 5895. The unit of 5895 is not given, so it is not possible (with the given information) to convert it into kilometers.
