Best ResponseYou've already chosen the best response.0Well, in this case I'd start with the realization that 10 = 5*2. How do you imagine that might help?

Best ResponseYou've already chosen the best response.010 is your lcm yes. Because 10 is a multiple of 10, (10*1 = 10) and 10 is a multiple of 5 (5*2 = 10)

Best ResponseYou've already chosen the best response.0Ok, & from there what do I do

Best ResponseYou've already chosen the best response.0Yes, 10 is your lcm. 10 is a multiple of 10. 10 is a multiple of 5. Therefore 10 is a common denominator for 10 and 5. You need to turn the 2/5 into a fraction with a 10 in the denominator. To do this you can always multiply the top and bottom of the fraction by the same thing (in this case 2)
