In mathematics, fractions are used to represent parts of a whole. The fraction 1/3 represents one-third of a whole. To convert 1/3 to a decimal, we need to divide the numerator (the top number) by the denominator (the bottom number).
To convert 1/3 to decimal, follow these steps:
Divide the numerator by the denominator: 1 ÷ 3 = 0.33333...
Continue dividing until you reach the desired number of decimal places: For example, if you want two decimal places, your answer will be 0.33.
