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.
Your answer cannot be MORE precise than the least precise measurement. For addition and subtraction, look at the decimal portion (i.e., to the right of the decimal point) of the numbers ONLY. Here is what to do: 1) Count the number of significant figures in the decimal portion of each number in the problem. (The digits to the left of the decimal place are not used to determine the number of decimal places in the final answer.). 2) Add or subtract in the normal fashion.
