3 dB is a way to describe the amount by which power increases when it doubles.
1 dB = increase 26%
2 dB = increase 58%
3 dB = double
4 dB = 2.51 times
5 dB = 3.16 times
6 dB = 4 times (3 dB + 3 dB = double double)
7 dB = 5 times
8 dB = 6.31 times
9 dB = 8 times (3+3+3 = double double double)
10 dB = 10 times
Similarly
-1 dB = decrease 26%
-2 dB = decrease 58%
-3 dB = halve
-4 dB = decrease 2.51 times
...etc...
The equation is:
dB change = 3 log2 ( final power / initial power )
Edit:
The more "official" equation used to compute a decibel Gain/Loss when comparing power values is this:
GdB = 10*log10(Pout/Pin)
Where GdB is the gain in power (if the value is negative, it means loss)
and Pout is the power level seen at the output
and Pin is the power level seen at the input
Also, 0 dB means no change in power.
Note: If you're measuring an amplitude (like a Voltage or Current value), then the decibel equation increases by a factor of 2:
GdB = 20*log10(Pout/Pin)
So, to double an amplitude, a 6dB increase would be required.
In other words, take the values at the top of this answer, and double the left side of the equation, and that's how it works with amplitudes.
Lastly, it's important to understand that when multiplying in the linear world, you are adding in the decibel world. If you double a power level 2 times (e.g. 10 watts -> 20 watts -> 40 watts), you are multiplying 4 fold, but you are increasing by 6 dB (3dB + 3dB = 6dB).
BUT if your talking about audio (sound) 1db is the smallest change in sound volume the human ear can detect.

70/320 is one.
320/1120 = 32/112 = 16/56 = 8/28 = 4/14 = 2/7
320 As 8:1 is 7 different (8-1) then divide 280/7 to get 40 Then 40+280 = 320 and 320/40 = 8 so is still 8:1 ratio.
We ran a Rental Cat 320 for 7 hours and averaged 6 gallons per hour consumption.
320 is divisible by 2, 4, 5, 8 and 10. Those are only the whole numbers, though. It can be divided by 2, 3, 4, 5, 6, 7, 8, 9 and 10, but it equals a decimated number. 320/2=160. 320/3=106.666666667. 320/4=80. 320/5=64. 320/6=53.3333333333. 320/7=45.7142857143. 320/8=40. 320/9=35.5555555556. 320/10=32. So, technically, 320 can be divided by every number, even ones higher than it (for example, 320/1234=0.25931928687). I dislike mathematics because of this large complication. So, in the end, you should have asked "What is 320 divisible by in whole numbers: 2, 3, 5, 9 or 10?" because this also would have been correct in English grammar. Hope this helps and doesn't just confuse you like it does to me... he he.
One machine produces 320 bottles in a day. So, four machines would produce 4 x 320 = 1280 bottles in a day. In 7 days, the number of bottles produced by 4 machines would be: 1280 bottles/day x 7 days = 8960 bottles. Therefore, 4 machines would produce 8960 bottles in 7 days.
