Your answer is .. First, we have to turn our mixed fractions into an improper fraction. =4 1/8 which is 33/8(4 x 8 + 1).
Our next mixed fraction, we have 1 1/7 which is 8/7(1 x 7 + 1).
Now, we have the get the same denominator in order to subtract. SO, both 8 and 7 goes in to 56. So we multiply both mixed fractions to get the same denominator. (Tip: what ever you do to do numerator, you do to the denominator; and the other way around). 33/8 : 33*7=231 and our denominator, 8*7=56 So our improper fraction now, 231/56
Our next fraction 8/7, 7*8= 56 and our numerator 8*8=64. =64/56
So, now we subtract. 231-64= 167 and our common denominator. 167/56
Now we divide 167 by 56 which is 2 and remainder is 55. So, you should end up with a mixed fraction, 2 55/56.
