Stuck on this as well. I think you need to take 29/35 \ 41/12, which then we get a common denominator of 420 and I really wouldn’t mind lightening it up, but I digress. So 348/420 / 1435/420 which gets rid of the 420, so 1435/358 is the entire job. We then need to subtract what we already used which is the fraction amount 42/12 or 3.42. Sooo 4.12-3.42=.70. And they don’t have enough cause they need .75. And I can tell you after have many houses painted, this situation never happens and I want my Wednesday night back
