Step by step

The question

Question: round 3.476 to the nearest tenth.

Round 3.476 to the nearest tenth

1 Find the place

The nearest tenth means the tenths place.

In 3.476, the tenths digit is 4.

3.476

2 Look at the next digit

Now we look at the next digit to the right.

It is 7.

5 or more: we round up, the tenths digit goes up by 1.

4 or less: we round down, the tenths digit stays.

5 or more → up: digit + 1
4 or less → down: digit stays

7 is 5 or more, so we round up.

7 is 5 or more → round up

3 Write the rounded number

The tenths digit 4 goes up by 1.

The digits after it are dropped.

So 3.476 rounded to the nearest tenth is 3.5.

The sign ≈ means about.

3.476 ≈ 3.5

Let's look back.

First: find the place.

Then: look at the next digit.

Last: write the rounded number.
