You have to create both sides of the equation using only the 9 cards, so you can't have 667/1271 on one side like that. So really, you have to make 667/1271 twice, and set those two things equal to each other to make the equation.

The solution I came up with is (29x(69-46)/(41x(93-62))=667/1271. It is a true equation, but I don't understand why it's not accepted.

Got the answer, but struggled with formatting to get it accepted by checker

Using * for multiplication rather than x worked fine for me - I assumed left to right math without parentheses rather than standard math precedence order although with only multiplication and division it didn't matter. Several different solutions with the same numbers will work, although I didn't try them all on the website.

I definitely misunderstood the challenge. I wrote one long equation that equaled 667/1271. Instead of two equations that equal each other and both equal the desired number. Didn't realize my mistake until I tried to type a square root symbol into the solution.

Okay, I figured out my 'mistake'; I was using the actual multiplication symbol (×), instead of the required lower case x. In my view, either should be acceptable, but that's for M to decide.

What's the equation you're trying to type in? Seems to work for me when I type [warning: full spoiler] (29/41)x(46/62)=(58/82)x(69/93). But I've tried a few different formats and equations and they all seem to work.

I came up with a correct solution which I confirmed with the answer in the back of the book. However, I've tried several formats of my equasion in the answer space on this site (including the ones in the explanation and the illustration), but nothing is accepted as correct. What's the proper format?
