So you would need to divide. so you would to the backwards c to make the first fraction improper. so it would be 7/2 divided by 7/1. then we would need to do the keep change flip and that will give us 7/2 x 1/7. then you just multiply. that would give us 7/21.

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.
