Answers (1)

As we learnt in 

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.

- wherein

2.5 × 1.25 = 3.125

Since 2.5 has two significant figures, the result should not have more than two significant figures, thus, it is 3.1.

 

 

The solution is 3.8 as it has 2 significant digits, just as 2.5
