10th grade geometry find the unknown length based on the given information lj is to jn as mk is to kp. lj = 8 , jn = ? , mk = 14 , kp = 6 . it's supposed to be set up like 8 over x = 14 over 6

MK to KP is 14:6

LJ to JN is 8:X

8/14 = X/6

X= 6 x 8 / 14 = 48 / 14 = 24 / 7 = 3 3/7

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.
