3%2F5-1%2F8 Start with the given expression




In order to subtract these two fractions, these fractions need to have a common denominator.


In order to do that, we simply find that the LCM of 5 and 8 is 40 (note: if you need help with finding the LCM, check out this solver)


Now we need to get each denominator to 40



%288%2F8%29%283%2F5%29-1%2F8 Multiply 3%2F5 by %288%2F8%29


24%2F40-1%2F8 Multiply 3%2F5 and %288%2F8%29 to get 24%2F40



24%2F40-%285%2F5%29%281%2F8%29 Multiply 1%2F8 by %285%2F5%29


24%2F40-5%2F40 Multiply 1%2F8 and %285%2F5%29 to get 5%2F40



Since both fractions have a common denominator of 40, we can now combine the fractions


%2824-5%29%2F40 Combine the fractions


19%2F40 Subtract the numerators



So

3%2F5-1%2F8=19%2F40
