Solve using the Division Method

A fraction is made up of two parts: the numerator, which is the number on top, and the denominator, which is the number on the bottom. We can find the decimal equivalent by dividing the numerator 3 by the denominator 21.

3 (numerator) ÷ 21 (denominator) = 0.143

This division gives us the decimal equivalent of the fraction.

So, when you change 321\frac{3}{21} to a decimal, your answer will be 0.143.
