Question

what is the lcm of 12x and 2x then?

Answer 1

12x

Answer 2

how do you do it?

Answer 3

2x is the smaller number
i first check if i can multiply a constant (integer) to it to make it 12x
6 * 2x = 12x

hence 12x is the LCM

Answer 4

oh, okay. Thank you. (:

Answer 5

yup ^_^

Answer 6

so then how would you do 5(x+y) 15(x+y)

Answer 7

same thing
5(x + y) is smaller
see if there's a constant that can be multiplied to get to 15(x + y)
3 * 5(x + y) = 15(x + y)

so it's 15(x + y)

Answer 8

okay. (:

Answer 9

cheers ^_^

Answer 10

Thank you. I don't like math very much.
