• Zeros that add value to the number.

What is the significance of zeros after the decimal point?

• They always add value to the number.

• They represent whole numbers.

• They can be ignored if not followed by a non-zero digit.

• They are always placeholders.

When do zeros in decimal numbers become placeholders?

• When they are at the beginning of the number.

• When they are followed by a non-zero digit.
