If I have 19732947.44
Asked to put this in 3 significant figures would this be 19700000
And in standard form to 3 significant figures would it be 1.97×10^7?

When we put the 5 0's after 197 why do we ignore the numbers that came after the dot?

the values after the decimal?
19700000.00 is the same as 19700000 , it's just neater and shorter to not include them.

Also the values after the decimal are not included in the Sig Figs so they would be truncated

Because if you put 19700000.00 it means that the number is exactly that and hasn’t been rounded. Writing 19700000 however shows that it has been done to 3sf.
