12:9, 12/9, and 12 to 9. The way I got 12 and 9 was by simplifying 60/45.
6: 1,3,2,6
7: 1,7
Factors of 6 are 1,3,2,6 because 1x6 (6x1) and 3x2. (2x3)
Factors of 7 are 1,7 because seven is a odd number so you can only multiply it by one and itself. (1x7 or 7x1)
18 = (240/100) x what;
what = 18 x (100/240);
what = 1800/240;
what = 7.5;
I assume you mean 3(16^7-39)?
16^7 is 268435456
268435456-39 is 268435417
268435417 multiplied by 3 is 805306251
Hope this helped.
114/2=57 I believe 57 is the correct answer
