180
15 times 12 is equal to 180.
The first five common multiples of 12 and 20 are: 12 x 5 = 60 20 x 3 = 60 12 x 10 = 120 20 x 6 = 120 12 x 15 = 180 20 x 9 = 180 12 x 20 = 240 20 x 12 = 240 12 x 25 = 300 20 x 15 = 300
To get your answer, divide 15 by 180. 180/15 = 12. Now, let's check your work! 15 x 12 = 180. Yay, it's correct!
