The number if significant figures in the result would not exceed the number in the equation with the best number of significant figures.

So, solution is 9.6 as 1.5 has just 2 significant figures

 

Multiplication and Division of significant figures -

 In these operations, the result must be reported with no more significant figures as are there in the measurement with the few significant figures.
