Expert Solution
Step 1

Rules for significant figures in the addition/subtraction : 

The answer will have the same number of significant figures after decimal as the number with lowest significant figures after decimal in the question have . 

Rules for place value: 

Let's assume a number:  123.45

In this number : 

Ones place = 3

Tens place = 2 

Hundredth place = 1

Tenth place =4 ( It is taken as 0.4 ) 

Hundredth place = 5 (it is taken as 0.05)
