First you turn both fractions into improper fractions
Next multiply 9/9 times 21/4
Then multiply 4/4 times 13/9
Now you have common denominators
Next find the answer to the problem
Finally , simplify your answer

Turn them into improper fractions. So,
21/4 - 13/9. Then give them common denominators; for this problem, just use their least common multiple; 36. So,
189/36 - 52/36. So you get,
137/36. Simplify,
3 29/36.
