Math A cookie cutter shark is 0.4 meter long, and a thresher
shark is 6 meters long. How many times as long as the
cookie cutter shark is the thresher shark?

The thresher shark would be 15 times as long as the cookie cutter stark because 6 divided by .4 would equal 15

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.
