Question

in a box 1/2 of the lights are red, 1/3 are blue, and 1/6 are green. The number of lights in the box is greater than 10. How many are there?

Answer 1

1/2 + 1/3 + 1/6 = 1

since the number has to be an integer

it must be at least 6, but it's greater than 10, so

6(1/2+1/3 + 1/6 ) = 6

12(1/2 + 1/3+ 1/6) = 12

18(1/2+1/3 +1/6) = 18

24(1/2+1/3 + 1/6) = 24

the number is 12, 18, 24, 30, 36, 42, or ....etc.

the number is 6n where n is an integer greater than or equal to 2
