You can either convert the decimal to a fraction and then subtract (3/4 - 0.5 = 3/4 - 2/4 = 1/4), OR you can convert the fraction to a decimal and then subtract (3/4 - 0.5 = 0.75 - 0.5 = 0.25).

An easy way to do this is to manipulate the original number and make sure to "undue" all the manipulations you did. For example: pick any number, add 3, subtract 2, subtract the number you started with, you have 1. Example explained: x + 3 - 2 - x = 1. More complex example: pick any number, multiply by 2, add 4, subtract 2, divide by 2, subtract 2, add 4, subtract the number you started with, you have 3. Explained: (((x * 2) + 4 - 2) / 2) - 2 + 4 - x = (2x + 2) / 2 + 2 = x + 3 - x = 3.
