Answer 1

Given  :  100 + 0.32 + 0.05  

To Find : The addition of (100 + 0.32 + 0.05) with  correct significant figures

100.37

100.4

100.3

100

Solution:

All non-zero digits are significant.

The leftmost nonzero digit is the first or most significant figure.

If there is a decimal point, the rightmost digit is the last or least significant figure

If there is no decimal point explicitly shown, the rightmost non-zero digit is the least significant figure

All digits between the most significant figure and the least significant figure are significant.

Count the number of significant figures in the decimal portion of each number

100 has 0 significant figures as no decimal

0.32  has 2 significant figures

0.05  has 1 significant figures

Least  significant figures =  0

100 + 0.32 + 0.05

= 100.37

= 100       with Least  significant figures =  0  after decimal

( the accuracy of the final answer can be no greater than the least accurate measurement )  

Hence The addition of (100 + 0.32 + 0.05) with  correct significant figures  = 100
