51/2 miles yesterday she rode 6 1/4 miles the difference in the length between the two rides is what fraction of the longer ride?

The question is looking for the difference divided by the longer ride. the longer ride is 6 1/4 miles, so now we need to find the difference. in order to do this we take the larger distance and subtract the smaller distance, so we would take 6.25 (i like decimals more)-5.5 and we get .75 or 3/4 of a mile. now we put .75 over 6.25 and simplify .125 or 1/8

Multiply 9 and 67. then multiply 3 with 67. lastly the answer that you got for 9x67 is to be subtracted by the answer you got for 3x67

Here is my answer, i'm sorry if you didn't understand my explanation
