Rounding or rounding off means replacing a number with an approximate value that has a shorter, simpler, or more explicit representation. For example, replacing $ 23.4476 with $ 23.45, the fraction 312/937 with 1/3, or the expression √2 with 1.414.

8 cze 2024 · Rounding a decimal to its nearest whole means converting a decimal with one digit after the point to a whole number closest to the original. Round 54.7 to its nearest whole number. Solution: As we know, the place we would round is 4. 7 is at the 10ths place. 7 > 5, adding 1 to 4 in 54, we get 55. The nearest whole number is 55.
Rounding means making a number simpler but keeping its value close to what it was. The result is less accurate, but easier to use. Example: 7.3 rounds to 7. Because 7.3 is closer to 7 than to 8. (Note: we round to whole numbers in these examples, but we can round to tens, tenths, etc) But what about 7.5? Is it closer to 7 or closer to 8?
