Please help with this question i attached an image to this. I would appreciate some hel[

part a is in the attached photo and part b=8/25

Step-by-step explanation:

1/5*4/5=4/25

4/25+4/25=8/25

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.

There is no image, or it's not working.
