60,120,180 and multiples of 60
60, 120, 180 and so on.
105, 210, 315
Asking what six multiples of fifteen are is the same as asking how many are in six groups of fifteen. To find this you need to multiply: 6X15= 90
Assuming you are talking about starting at three, the next four multiples are six, nine, twelve and fifteen.The answer depends on next after what!
15, 30, 45, 60, 75, 90, 105, 120, 135, 150, 165, 180, 195, 210, . . .
They are: 105, 210, 315, 420, 525, 630, 735, 840, 945, 1050, 1155, 1260, 1365, 1470, 1575.
8, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88, 96, 104, 112, 120
Well since both 15 and 55 are both multiples of five, that would simplify to 3/11, after dividing both sides by 5.
15+15+15+15=60
First 15 multiples of 7: 7, 14, 21, 28, 35, 42, 49, 56, 63, 70, 77, 84, 91, 98, 105First 15 multiples of 9: 9, 18, 27, 36, 50, 54, 63, 72, 81, 90, 99, 108, 117, 126, 135There's many others that come after, but those are just fifteen out of all of them.
Fifteen feet is fifteen feet long.
