Kayak is 12 3⁄5 feet long. ava's kayak is 20 2⁄5 feet long. how much longer is ava's kayak?

The answer is 7.8 in decimal form
7 8/10 in fraction form

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.
