You need to start off thinking of what 60% means.
A percent is a ratio (fraction) of a given number divided by 100. Drawn as a fraction, it looks like this:
60
60% = ----- 100
Now, a bit of Junior High Algebra, and we can now write it as an
equation and solve for X.
60
---- x 120 = X
100
When we multiply fractions by whole numbers t is the equivalent of 60 120
---- x ---- = X
100 1 To multiply two fractions together, you multiply the top and the bottom
separately... 60 120 60 x 120 7200
---- x ---- = --------------- = -------- = X
100 1 100 x 1 100 and, the final step is to simply the fraction and (hope) that it can become a whole number again without any remainder...

120
No, 120 is a multiple of 60. 60 is a factor of 120.
60% of 120 = 120*60/100 = 72
The greatest common factor of 60 and 120 is 60.
Yes. 60 + 60 ------ 120
2x6 is 12 Add a zero (the zero from 20) and you have: 120
60 + 60 + 120 = 240
60 is 50% of 120
The least common multiple of 60 and 120 is 120.
120 / 2 = 60 !
