How do you subtract fractions?

One way you can subtract fractions is to change them into decimals, aligning the decimals vertically, then subtracting like you would with whole numbers, making sure to carry down the decimal. Another way that you can subtract fractions is to use the least common denominator (lcd). First, simplify the fractions. Then find the multiples of the denominators. When you find the multiple included in both lists that is the least, multiply the numerator and denominator by the same number in order to make the denominator into the lcd. Then, subtract the numerators and simplify the answer. Example: 2/3 - 1/2 = 4/6 - 3/6 = 1/6
