Fraction to decimal: numerator divided by denominator, quotient is decimal. Decimal component number: first look at how many decimal places there are in the decimal part, then add a few zeros after 1 as the denominator, and divide the original decimal by the numerator instead of the offer of the simplest fraction to differentiate it into the simplest fraction.

Examples are as follows:

1/2 is a decimal and 1/2 is a fraction. When converted to decimal, the numerator is divided by the denominator, that is, 1÷2=0.5, so it is 0.5 when converted to decimal.
