There are infinitely many possible answers.
Some examples:
1*129
10*12.9
10000*0.0129
5*25.8
-126
To determine what goes into 129, we need to find its factors. The factors of 129 are the numbers that can be multiplied together to give the original number. The factors of 129 are 1, 3, 43, and 129. This means that 1, 3, 43, and 129 can all divide evenly into 129 without leaving a remainder.

Here are a couple: - 258 x 2 -129 x 4 -86 x 3 -43 x 6 there are more, but you have to get into decimals.
129 * 106 = 13,674
129 multiplied by 122 is 15,738.
146 multiplied by 129 = 18,834
41,43,45 is the answer
When looking for factors, try out some small numbers, such as 2, 3, 5, 7. In this case, it is quite obvious that 129 is not divisible by 2. But if you continue trying, you see that it IS divisible by 3. Of course, if you divide 129 by 3, you get the other factor.
xy=-24 x+y=15 if y is not 0 x=24/y and y+24/y=15 y2+24=15y => y2-15y+24=0, delta = (-15)2 - 4 x 1 x 24 = 129 y = (-(-15)±sqrt(129)/(2 x 1) = (15±sqrt(129))/2 and then x = 24/y = 48/(15±sqrt(129)
These are all the whole numbers that go into 129 evenly: 1, 3, 43, 129.
