between significant digits are always significant. figures. Example: 5,007 has 4 significant figures. 3) Trailing zeros in a number are significant only If the number contalns a decimal polnt. Example: 100.0 has 4 significant figures. 100 has 1 significant figure. 4) Zeros in the beginning of a number whose only function Is to place the decimal polnt are not significant. Example: 0.0025 has 2 significant figures. 5) Zeros following a decimal significant figure are significant. Example: 0.000470 has 3 significant figures. 0.47000 has 5 signlficant figures. Determine the number of significant figures in the following numbers. 1. 0.02 6. 5,000. 4. 2. 0.020 2. 7. 6,051.006 3. 501 3 8. 0.0005 1. 4. 501.0 9. 0.1020 5. 5,000 10. 10,001 5 Determine the location of the last significant place value by placing a bar over the digit.
