It would be: 39 to 11
It is: 780/220 = 39/11
The multiples of 780 (which are infinite) are all divisible by 780, including these: 780, 1560, 2340, 3120, 3900, 4680, 5460 . . .
The answer is 780 780/65=12 780/26=30 780/12=65 780 is the lowest common multiple that each of the numbers all have in common.

Percent can only be used in comparison with something, with 100% being all of the reference.Let's say you have 220 dollars, then that's 100% of your money.110 dollar would be 100 x (110/220) = 50%55 dollars would be 100 x (55/220) = 25%440 dollars would be 100 x (440/220) = 200%
The proper factors of 220 are 2,4,5,10,11,20,22,44,55,110
Mine was 220 and I suppose they all are.
Not much of anything. The 220 volt appliance needs just that ... 220 volts in order to run. If it runs at all, it certainly would not be running at anywhere near peak efficiency.
The list of choices that you sent along with the question doesn't include any that can help at all.
in my opinion, at high temperatures and pressures the answer would be :- none, i.e all metal oxides can be reduced by hydrogen.
The factors of 780 are: 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
