5/9 times 3/5- You multiply 5x3 & 9x5 and get 1/3
5/6 times -1- Since it's one, you just add the negative : -5/6
3/10 2- (Did you mean 3/10x2?)- 6/10, which reduces to 3/5
5/6 times -2/5-Multiply both numerators (top numbers) & denominators, & get -10/30 (negative), which reduces to -1/3
5x/7 times 3/10-(Did you mean 5x, or was the x a typo?)- 15/70, which reduces to 3/14
9t/16 times 12/17-(Again, did you mean 9t, or was the t a typo?)- 108/272, which reduces 27/68
I'm not sure if you meant multiply all the numbers you listed or each pair, but I hope I helped.
