There is actually no specific formula to subtract fractions but rather a method to accomplish this. First you have to obtain a common denominatior between the two fractions in order to subtract. This is easiest when you just multiply the denominators.

If you have 1/4 and 1/9 you multiply the denominator to have a common one. This would give us 36. then you would have to multiply the numerators by the number you multiplied the denominator.

This means that 1/4 would become 9/36 because you multiplied the bottom by 9 in order to get 36. You can check to see if you did this right by simplifying the fraction and seeing if you got your original fraction. Once you have these new common fractions you simply subtract the numerators and put them over the common denominator.

9/36 - 4/36 = 5/36 which cannot be simplified
