14, 28, 42, 56, 70, 84, 98, 112, 126, 140, 15420, 40, 60, 80, 100, 120, 140, 160The LCM is 140.
240
100(56/140) = 40 %.
The LCM is: 200
The LCM is: 400
40 off 140 is 100. 40% off 140 is 84.
56/140 x 100 = 40 Therefore, 56 is 40 percent of 140.
The multiples of 20 are: 20, 40, 60, 80, 100, 120, 140, etc ...The multiples of 30 are: 30, 60, 90, 120, 150, etc ...The multiples of 40 are: 40, 80, 120, 160, etc. ...The lowest multiple common to 20, 30, and 40 is 120, so the LCM = 120
200
LCM 140 and 28 is 140.
