Yesterday grace drove 31 1/2 miles she used 1 1/4 gallons of gasoline. What is the unit rate for miles per​ gallon? im stuck can some one plz help me it would be a huge help

twenty-six miles over two gallons because the proportion for the original 13 miles to one gallon would be written 13/1 and, doing the same thing to the top and bottom, i multiplied by 2 and got 26/2

we can't see all full 4 options, but if this is the full option, than the very left one is correct:

-2/5 * -3 3/4

remake the question, adding a picture of all the question, or write down the full left and right answers.
