Answer:
a) 5
b) 4
c) 3
d) 3
e) 4
Explanation:
I use only one rule when the decimal is present, meaning you can see the decimal (as is the case with all of these).
When the decimal is Present, start counting sig figs from the Pacific (left) side of the number beginning with the first non-zero digit and count all the way to the end.
So, for example, in "a", the first non-zero digit starting from the left is 1, then continue counting all the way to the right side.
For "c", the first non-zero digit is the left most 4 (skip the first 4 zeros), then count all the way to the right side.
