Compare the decimals 9,135.40 and 9,135.4.

which comparison is correct?

a.
9,135.40 < 9,135.4

b.
9,135.40 > 9,135.4

c.
9,135.40 = 9,135.4

It would be C, because 9,135.40 and 9,135.4 have all the same numbers, except 9,135.40 has a zero at the end.
But when there is something like this.
9,135.40
9,135.4
You put a little invisible zero where a number should be.
So now it looks like this.
9,135.40
9,135.40
So, they would be equal. Hope this helped!

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.
