George ate four slices of pizza if this was 25% of slices at the dinner table how many slices were at the table to start with

If 4 was 1/4 of the pizza you do 4x4 to get a total of 16 slices.

25% = 1/4
25% of 100%=1/4
you will need to multiply 4 times 4 to see how much pizza was at the table to start with.

So in short your answer is 16.

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.
