Mathematics-Compact Form of Decimals

Compact form of decimal in mathematics - We can write the Decimals in different ways. In fractional format and words format. Or we can write this in expanded or compact form.
When a number is written in the form 246, we can easily say that it is in compact form. Suppose we written it in 2 × 100 + 4 × 10 + 6 × 1, we can say that it is in expanded form.

We can represent decimals in 0.674, the compact form. Also represent it in expanded form like ( 6 × 1 / 10 ) + ( 7 × 1 / 100 ) + ( 4 × 1 / 1000 )
