So in order for you to do this problem you have to start by turning the 2 1/5 into a mixed number. And you would do that by multiplying the 2 and the 5 which is 10 and adding a 1 which is 11 and put it over the denominator
2x5=10+1=11/5
And for the next part it’s going to form the problem
11/5 / 4/5
We would then want to change the sign since we cannot divide a fraction with another fraction this way so we would do KCF
Which stands for Keep, Change and Flip
We would Keep the first fraction which is 11/5 and change the divide sign to a multiplication sign and Flip our second fraction being 4/5. It would then look something like this:
11/5 x 5/4
Then multiply across and you would get 55/20 as your answer but it would be better to simplify it to being 11/4
