Rounding to the nearest whole number

It is not always necessary to give the exact number. For example, if there were $$54,785$$ inhabitants in a town, you could say that its population was approximately $$55,000$$.

By doing this we have rounded $$54,785$$ to the nearest thousand to give $$55,000$$.

Rounding to the nearest 1,000

What is $$1,484.5$$ to the nearest $$1,000$$?

It is between $$1,000$$ and $$2,000$$, but it is closer to $$1,000$$, so round down.

$$1,484.5$$ rounded to the nearest thousand is $$1,000$$.

Rounding to the nearest 100

What is $$1,484.5$$ to the nearest $$100$$?

$$1,484.5$$ is between $$1,400$$ and $$1,500$$, but it is closer to $$1,500$$, so round up.

$$1,484.5$$ rounded to the nearest hundred is $$1,500$$.

Rounding to the nearest 10

$$1,484.5$$ lies between $$1,480$$ and $$1,490$$, but it is closer to $$1,480$$, so round down.

$$1,484.5$$ rounded to the nearest ten is $$1,480$$.

Rounding to the nearest whole number

$$1,484.5$$ lies between $$1,484$$ and $$1,485$$ and it is exactly halfway between them. In this situation round up.

$$1,484.5$$ rounded to the nearest whole number is $$1,485$$.
