have a pie that says to cook for 3 mintues in an 850 watt microwave. I have a 1200watt microave so how long should I cook it for? Can you also tell me what you did to figure the answer out.

All other things being equal, which they never are, 3 minutes @ 850 watts = 2550 watt-minutes.
In a 1200 watt microwave, 2550 watt-minutes / 1200 watts = 2.125 minutes, or 2 minutes 7.5 seconds.
Note, however, this ignores the fact that it takes time for heat to transfer through materials (you cold not cook this in a 2550 watt microwave for a minute - it would be cold on the inside.)

All microwaves allow you to reduce the power to nine different levels. The tenth level is 100% power ( do nothing to set).
If I press 2 I get 20% of my microwaves power
If I press 8 I get 80% of my microwaves power
Now we know you have a 1200 watt power at 100% so that means
1200 = 100x (percent)
12= x
so each percent is 12 watts of power.
now, divide
850 / 12= (70.83%)[of your microwave's power]
so roughly you need your microwave at 70% power level, but maybe give 3 seconds longer to adjust for the extra fraction of a percent.

Most likely the pie will burn in the 1200 watt microwave.
One egg takes 3 minutes to boil, sooo 12 eggs 12 minutes ?
You should ask a cook not a mathematician to answer your questiom

Energy = power * time
power is measured in watts.
If you assume that you'd want to put in the same amount of energy, a fair assumption, then
850*3 = 1200*t
Now just solve for t.

3*850/1200 = 2' 7", but don't expect it to be fully cooked.
