List the multiples of both 12 and 9:

12, 24, 36, 48, 60

9, 18, 27, 36, 45

The lowest common multiple is 36.

This will make the fixtures and bulbs equal.

This means they bought 3 packages of light figures 3 x 12 = 36)

And bought 4 packages of bulbs ( 4 x 9 = 36)

Find out LCM of 9,12

  • LCM=2(2)(3)(3)=36

Now

No of light packages=36/12=3

No of light bulbs=36/4=9
