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.
To divide a decimal number by a whole number: 1  Use Division or Long Division (ignoring the decimal point). 2  Then put the decimal point in the same spot as the dividend (the number being divided).he trick is to change the number we are dividing by to a whole number first, by shifting the decimal point of both numbers to the right: Now we are dividing by a whole number, and can continue as normal. It is safe to do this if we remember to shift the decimal point of both numbers the same number of places.
