Question

The number 3.453 has two 3s. Why does each 3 have a diffrent value

Answer 1

There is a three before the decimal that represents the ones place to where it's just 3. The three after is in the thousandths place. If you need more explanation message me;)

Answer 2

The given number is 3.453.

The first 3 that is before the decimal is at ones place.

Or
`3*1=3`

But the second 3 which is after the decimal is at thousandth place.

Or
`(3)/(1000)=0.003`

Hence, you can clearly see the different values of both three's. These are different due to the place values.
