-8/15 a = 9/10

-80 = 135a

-80/135 = a

-0.59 = a

The way you typed it .....
-8/15 a = 9/10
would mean:

(-8/15) a = 9/10 , by the order of operation
-80a = 135
a = -135/80 = - 27/16 = - 1.6875

Ms Sue interpreted it as the way you probably meant it ...

-8/(15a) = 9/10

a = -16/27 = -.59259259.. (the 592 is repeated)
