Answer:

  • 3 and 4 packages

Step-by-step explanation:

We need to find the LCM of 12 and 9.

  • 9 = 3*3
  • 12 = 2*2*3

Their LCM is:

  • LCM(12, 9) = 2*2*3*3 = 36

Number of light fixtures and light bulbs is 36.

Number of packages will be:

  • 36/12 = 3 and
  • 36/9 = 4 respectively.

Step-by-step explanation:

First finding LCM of 9 and 12

9 = 3 Γ— 3

12 = 2 Γ— 2 Γ— 3

LCM = 3 Γ— 2 Γ— 2 Γ— 3

LCM = 36

Now,

No. of light fixtures = 36/12 = 3

No. of light bulb = 48/12 = 4
