Question

Help a girl out with math!! i really can’t seem to understand how they get the different numerators.

Answer 1

First you find the LCM of your denominater...
in this case 6 and 12, so the LCM is 12
then you need to make the denominator number to match your LCM
at 1/6 your denominator is 6 so you need to multiply it by 2 to become 12 but remember if you multiply your denominator you must also do the same with you numerator... so your fraction 1/6 both the numerator and denominator must multiply with 2... then we get 2/12
at 5/12 you denominator already matched the LCM so we not need to multiply it...
thats it... hope you understand... :)

Answer 2

When you find the common denominator, multiply the numerator by the same number you do the denominator.

5:  1/6 - multiply both the numerator and denominator by 2: 1*2/2*6 = 2/12

2/12 < 5/12

6:

LCM would be 33

2/3 = 2*11 / 3*11 = 22/33

8/11 = 8*3 / 11*3 = 24/33

22/33 < 24/33
