You can add a zero to them (multiply them by 10).
1 x 12
2 x 6
3 x 4
10 x 12
20 x 6
30 x 4
40 x 3
60 x 2
120 x 1
It can have 120 combinations . . .
Always remember that multiplication is the inverse/opposite of division, so they can be used to check each other. For example: Let's say the problem is 120 / 6. Whatever you think is your answer, you can multiple by 6 and that result should be 120. Is 120 / 6 = 10? No. The quick check is 10 * 6 = 60, which does not equal 120. Is 120 / 6 = 20? Yes! We know this is right because 20 * 6 = 120.
5*4*3*2*1 = 120 combinations. * * * * * No. The previous answerer has confused permutations and combinations. There are only 25 = 32 combinations including the null combinations. There is 1 combination of all 5 numbers There are 5 combinations of 4 numbers out of 5 There are 10 combinations of 3 numbers out of 5 There are 10 combinations of 2 numbers out of 5 There are 5 combinations of 1 numbers out of 5 There is 1 combination of no 5 numbers 32 in all, or 31 if you want to disallow the null combination.
Possible 5 digit combinations using 5 digits only 1 time is 5! or 5*4*3*2*1 or 120. Using 5 digits where numbers can be used 5 times is 55 or 3125.

To answer this question you need to start with the "... combinations you wrote for 12, 18 and 21". Notice that the numbers in the second set are each 10 times the numbers in the first set. Combinations for numbers in the second set can be found by adding "*10" or "*5*2" to the combinations for the first set. You could also say: 12 = 2*2*3; 120 = 2*2*3*5*2 = 4*15*2, and many other variations on this theme.

12 is the multiplier and 10 is the multiplicand. The product is 120.

28.5 % = 0.285; "of" in words corresponds to multiplication; 120(0.285) = 34.2.
