how to divide fractions using calculators?


To divide fractions proceed as you usually do with any number. Just make sure to enclose each fraction in parentheses. You may want to remember a simple rule: To divide a fraction by another, multiply the first one by the reciprocal of the other:

whats the major problem with supergiants


They're big, heavy and awkward to use, and the image is over-magnified for the size of the objective giving less than ideal image quality and brightness. A general rule (especially if using for astronomy) is that the objective divided by the magnification should never be less than 5. With 20x80's it's a less than ideal 4 so you'll miss out on many fainter objects completely. They can be excellent for lunar observation though as the Moon is so bright.

The high magnification also makes them almost impossible to hand hold steadily enough unless a tripod (or monopod) is used, adding more bulk and awkwardness.

Create an equation to calculate a change in gear size on a jeep.


If the gears have been INCREASED the speed etc will be less.
Say it's increased by 18%.In theory,at 100mph real speed, the speedo will read 18%less.i.e. 82mph.
If the speedo is driven off the g/box,all this has to be taken into account.
If the speedo is driven off the wheels(and the wheels have not changed at all)All that will happen is the engine revs will have decreased by 18%.
So,To work out the difference.Divide the distance travelled by 100 and then multiply the answer by 82.(82 is the remaining % of the original)
So if 150 miles is divided by 100=1.5
1.5 is multiplied by 82=123 miles.
Hope this helps

80 minute CDR's are generally 700mb cds. It all depends on the file size of your images.
