If −15/9y < 11/13 mean:
−( 15 / 9 ) y < 11 / 13
then multiply both sides by 9
- 15 y < 99 / 13 Divide both sides by - 15
When you multiply or divide both sides of an inequality by a negative number, you must reverse the direction of the inequality.
y > ( 99 / 13 ) / 15
y > 99 / 13 * 15
y > 33 * 3 / 13 * 5 * 3
y > 33 / 13 * 5
y > 33 / 65
−( 15 / 9 ) y < 11 / 13
then multiply both sides by 9
- 15 y < 99 / 13 Divide both sides by - 15

y > ( 99 / 13 ) / 15
y > 99 / 13 * 15
y > 33 * 3 / 13 * 5 * 3
y > 33 / 13 * 5
y > 33 / 65

Correction
y > ( 99 / 13 ) / - 15
y > - 99 / 13 * 15
y > - 33 * 3 / 13 * 5 * 3
y > - 33 / 13 * 5
y > - 33 / 65
y > ( 99 / 13 ) / - 15
y > - 99 / 13 * 15
y > - 33 * 3 / 13 * 5 * 3
y > - 33 / 13 * 5
y > - 33 / 65

I agree with Bosnian's answer.
check your typing of the question.
Did you perhaps mean
−15/(9y) < 11/13 ?
