Note before we start working on solving this, the denominators 10, 9, and 8 mean the answer is probably not going to be a "nice" fraction....

Multiply by a common denominator, 8*9*10 = 720. (We could spend some time to find the LEAST common denominator; but the amount of simplification of the calculations would probably not be worth the time and effort.)

Simplify the fraction or convert to decimal if desired or required.
