You want to make both denomiator's in this problem the same, So you have: 23−26=?We can find the LCM
(Least common mulitple) of these numbers, which is 6 because 6*1 = 6 and 3*2 = 6 So now we know we have 26but we need to change 23 to a denomiator of 6, we
can do this by simply changing it to six and to find the numerator we divde 6 by 3 and then multiply the quotient by the numerator of 2/3 which is to
so 2*2 is equal to 4 so now we have 46−26=26
So now we know 26 is or answer. whic reduces to 13
