Answer :
Reduce your fraction 2/4 down to 1/2, and then find the smallest common factor of 2 and 6 (which happens to be 6). Since you multiply 2 by 3, then you have to multiply your numerator by 3 also, giving you 3/6. Since your denominators match, it means you have found the answer.
2/4 = x/6
2/4 = 1/2 = 3/6
you find the least common denominator which will be 12
2/4 = 6/12
you multiply 4 x 3 to get 12 so you have to multiply 2 x 3 and get 6.
now if you divide both numbers 6/12 by 2 then 6/12=1/2.
another way to look at this one is 2 is half of 4, so what is half of 6.
../.... = .../......
