Frequently Asked Questions
What is the rule for rounding?
Look at the digit immediately to the right of the place you're rounding to. If it's 5 or more, round the target digit up; if it's 4 or less, leave it as is — then drop everything after it.
How do you round to the nearest tenth?
Look at the hundredths digit. 47.386 rounded to the nearest tenth looks at the 8 (≥5), rounding up to 47.4.
How do you round to the nearest 10 or 100?
Divide by 10 (or 100), round to the nearest whole number, then multiply back by 10 (or 100). This is the same rule applied one place value higher.
