Carlos rode further than on Saturday by  107/56 miles.

Step-by-step explanation: We are given Carlos biked on Saturday = 139/8 miles.

He biked on Sunday = 135/7 miles.

Let us find which fraction is greater by finding common denominator.

LCM of 7 and 8 is 56.

Therefore, Common denominator of 139/8 and 135/7 is 56.

Converting each fraction as denominator 56.

139×7/8×7 = 973/56

135×8/7×8 =  1080/56.

We can see that 1080/56 is greater than 973/56.

On subtracting 973/56 from 1080/56, we get

1080/56 - 973/56 = 107/56
