Homework Help: Mathematics

what is (5 3/5 divided by 1 5/9) - (1 1/5) squared?

what is (five and three over five divided by one and five over nine) minus (one and one over five) squared?

the answer is suppose to be 2 4/25 (two and four over twenty-five) but I'm not sure how to work out the second part of the question, (1 1/5) squared.

1 1/5 = 6/5

6/5 squared = 6/5 * 6/5 = 36/25

5 3/5 = 28/5

1 5/9 = 14/9

(26/5)/(14/9) = (26/5) * (9/14) = ?

Subtract 36/25 from ?.

I hope this helps. Thanks for asking.
