Best Answer: To add a fraction to a decimal easily, you will have to convert them both into the same form. For example if you wanted to calculate 1/2 + 1.5, you could say 1.5=3/2, so 1/2+3/2 = 4/2 = 2. Or you could say that 1/2 = 0.5, and 0.5 + 1.5 = 2.
Write the shared denominator as the denominator of a new fraction, off to the side. 3. Add or subtract the numerators of the fractions you're dealing with, then write the result as the numerator of the new fraction, off to the side. This is your answer.Remember: 1  You can switch the order of the numbers you're adding with impunity. 2  So 3 + 5 + 7 is the same as 5 + 7 + 3.teps. 1. Make sure that the denominators of every fraction that you're going to add or subtract are the same. 1  If the numbers are different, you can't add or subtract the fractions as-is.
