Reduce the Decimal 0.2040 to Its Simplest Fraction Form

Trailing zeros are zeros that come after the last non-zero digit in a decimal. In $0.2040$, the final zero is trailing because it's after the 4.

Trailing zeros don't change the decimal's value - they're just placeholder zeros. But zeros between digits (like the zero between 2 and 4) are significant and show the actual place value!

Yes! Both decimals have exactly the same value. The trailing zero in 0.2040 doesn't add any mathematical meaning - it's just extra notation.

Only remove zeros at the very end of the decimal. Start from the right and work left - stop as soon as you hit a non-zero digit!

If you have something like $3.000$, you can remove all trailing zeros to get $3$ or write it as $3.0$ - both are correct!
