7
Adding the Barometric Reading Adding initial 9 or 10 at the beginning of the given number depend on which will make the number closer to 1013. Move the decimal point to the left once

8
Adding the Barometric Reading Adding initial 9 or 10 at the beginning of the given number depend on which will make the number closer to 1013. 188 Initial 9 or 10? 918.8 or 1018.8 Which is nearer to 1013? 1018.8

10. What is the barometric pressure 998.7 is nearer to 1013 than 1098.7 Answer: 998.7 mb In tenths of mb

10
11. What was the barometric pressure three hours ago? 998.7 minus 1.1, since the barometer has been rising, it was lower in the past, and the amounts are reported to the nearest tenth of a millibar Answer: 997.6 mb In tenths of mb
