Just a small maths question that i cant answer?

Question

if jack owns 4 beans and tanya owns 9, how many does brian own if it is a third of the square root of the added together common multiples of both jack and tanyas beans?

Answer 1

is this supposed to be a trick question?  There are an infinite number of common multiples of 4 and 9.  1/3*sqrt(infinity) = infinity

Answer 2

"common multiples" means a number divisible by both 4 and 9.

Work backwards with the facts:

1. Find a common multiple of 4 and 9 (multiply the two will give you one).

2. Take the square root.

3. Take 1/3 of that.

I get 2.

Answer 3

I don't know what "added together common multiples" is, I'm assuming you mean the sq root of the two terms multiplied

Brian = 1/3 * sq root (4 x 9)

=1/3* sq root (36)

=1/3 * 6

=2

Maybe this question belongs also in a proper english and grammar section?
