Question

Round 628.308 to the nearest tenth.

Answer 1

628.3 is the round number.

Explanation:

Decimal numbers have different names, depending its position. The first decimal is called tenth, the second decimal is called hundredth, and the third decimal is called thousandth.

So, in this case rounding to the tenth means we need to round until number 3, because it's the tenth in our decimal number.

Next, we need to apply approximation rules to round the number.

• If the next number to the tenth is five or higher, the '3' becomes a '4'.
• If the next number to the tenth is lower than 5, we maintain the '3', we don't change anything.

That's why our approximation to the tenth results 628.3
