39x3=30x3+9x3
117=90+27
117=117
39x3=30+9x3
117=30+27
117=57
39x3=300x3+9x3
117=900+27
117=927
39x3=30x3+9
117=90+9
117=99
So the first one is correct.

They own a total of 120 CDs.
GIVEN:
Ella: ratio of rock music to total CDs that she owns 25/40
Paolo: has 50 rock music CDs. The ratio of rock music to total CD is equal to Ella's ratio.
Proportion: a/b = c/d where ad = bc
25/40 = 50/x
25x = 40 * 50
25x = 2000
25x / 25 = 2000 / 25
x = 80 total of Paolo's CDs
Total of Ella's CDs = 40
Total of Paolo's CDs =<u> 80</u>
Total CDs in all 120
