What is the value of x in 1.2÷0.3= x÷0.4

multiply both sides by .4 to isolate the x variable.



x = 1.6

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.
