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 front end estimate is 800. But estimating a single number, in isolation and without context, is a complete waste of time. It all comes down to the context of what needs to be done with the number.If I had to add 779 to 1 trillion, I would estimate it as 0.If I had to add 779 to 0.0000000001, I would use the number as given, or possibly the front end estimate. If I had to divide it by 7, I would estimate it as 770, because 770/7= 110. If I had to divide it by 10, I would estimate it as 780, because 780/10 = 78.
