3.12: 3 significant 72.10: 4 siginificant 0.13: 2 siginificant


After we know how many significant a number have, that me show you how to know how many significant after the multiplying

That me show you some different type of examples:

1. 5.30 X 28.3 = 150------3 siginificant

3 significant 3 significant
IF THE TWO NUMBERS OF ARE SAME, WE SHOULD AS SAME AS TWO SIGNIFICANT FIGURES
2. 0.25 X 52.78 = 13---------2 siginificant ‚Äč(we chose the least number of significant figures as the answer)
2 significant 4 significant
IF THE TWO NUMBERS OF ARE NOT SAME, WE SHOULD AS SAME AS THE LEAST NUMBER OF SIGNIFICANT FIGURES
