15.8 Take the number after your desired decimal place. If it's 4 or lower, then the number at the desired decimal place stays the same (in this case, it stays .8). If it's 5 or higher, then the number at the desired decimal place raises by 1.E.g. 15.869 rounded to 1 decimal place is 15.9.E.g. 15.849 rounded to 1 decimal place is 15.8.

Short answer: 105 Explanation: A whole number is one without a decimal. When you're rounding, take a look at the decimal. if the decimal is less than .50, then you round down to the current whole number, in this case 105. If the decimal is .50 or above, you round up to the next number, in this case, 106. Since the decimal is .27 we round down to 105.
Oh honey, 30.974 rounded to the nearest whole number is 31. But if you want to be fancy and round it to one decimal place, it's 31.0. So take your pick, darling.
To round 7.346 to 1 decimal place, we look at the digit in the second decimal place, which is 4. Since 4 is less than 5, we simply truncate the number after the first decimal place. Therefore, 7.346 rounded to 1 decimal place is 7.3.
Rounding never increases the number of decimal places.0.6 is not only already rounded to two decimal places, it'salready rounded to one decimal place.
that answer is all ready rounded to the ten thousand because it is a whole number meaning not a decimal number.. if it was .1374692 then you would take the ten thousands place (1st one is tenths, 2nd one hundreds, 3rd one thousands, 4th one ten-thousands, and so on. so .1374692 take a look at the 4 position from the decimal point which is 4 and look to its right if the number is higher than or equal to 5. 4 becomes a 5 so like this .1375 thats your answer!!
Subtract 0.5
Well, darling, when you round 4.99 to the nearest whole number, it becomes 5. But if you want to get technical, 4.99 rounded to the nearest tenth is still 5. So, take your pick and go forth with your newly rounded number.
8.4 x 106 Basically, since this is all on the left side of the decimal point, you take the first 2 digits, round them (need to look at the 3rd digit '9' for rounding), then you set the 10n exponent , where n is the number of decimal places it takes to get from the shortened number to the original number (rounded)
Take the number and divide it by 100.
