No. If the denominators are the same, you subtract the numerators. If the denominators are different you have to find the least common denominator.
The English term 'subtract' means 1: take off or away; 2: make a subtraction
Subtract their numerators, and put on top of the common denominator. Thus, for example, 5/3 - 3/3 = 2/3. Works for addition, too (add the numerators).
When one number is subtracted from another number, the result is known as the difference.
Use a calculator if you're too stupid to solve it.
