Expert Answer

If you're rounding to the nearest whole number and there is a .5 in the tenths place, then you should round up (e.g., 1.5 would round up to 2). However, if you're rounding to the nearest tenth and there is nothing in the hundredths place after the .5, leave it as it is.

Expert Answer

Look at what is in the thousandths place and round up or down based on that. Your result should have 2 decimal places, unless there is a 0 in the hundredths place and something smaller than 1 in the thousandths place. For example, 7.586 would round up to 7.59. 2.324 would round down to 2.32. 6.301 would round down to 6.3.

How do I round 7.449 to the nearest tenth?

Because the hundredths place is 4, do not round up the tenths place. Leave it alone, and eliminate everything to the right of it. 7.449 rounds to 7.4 if rounding to the nearest tenth.

How can I round 3.993 to the nearest tenth?

Look at the hundredth's place and you see it needs to round up. Since the tenth's place already has a 9, then the one's place must round up as well. 4.0 is the correct answer.

Question

How do I round to the nearest whole number?

Donagan

Top Answerer

Look at the digit in the tenths column (just to the right of the decimal point). If it's less than 5, keep the units column digits as it is and just get rid of the decimal (for example, 1.4 would be rounded to 1). If it's 5 or more, round the units column digit up by 1 and get rid of the decimal (for example, 18.6 would be rounded to 19).

If I were to round 15.625 to the nearest tenth, would I push the 5 over to the tenths place, or leave it there?

No, the nearest tenth would be either .6 or .7, depending on the digit in the hundredths place. Because that digit is a 2, you would leave the .6 in the tenths place and not round it up.
