The diner has 5/8 of beef pot pie and 3/4 of a chicken pot pie Mr. Lin bought the one that had one more left how could Damiá and Darby write those fractions with a common denominator to figure out which pot pie had more left ?

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
