22 out of 30 ... since 30 is twice as large as 15, the answer must be half of 22, or 11.
Put another way, 22 and 30 are twice as large as 11 and 15.
11/15 = .733 = 22/30

-- take the number of [ miles per hour ]-- multiply by [ 22/15 ]-- the answer is the number of [ feet per second ].30 mph = 44 fps
LCM(15, 22, 30) = 330
For the values 30, 22, 15 the LCM is: 330

The Least Common Multiple (LCM) for 15 22 30 is 330.
It is: 22/30 = 11/15 simplified
25/30 + 22/30 = 47/30
30/22 = 15/11 = 1 and 4/11
