Explanation is poorly written. Usually they are very clear, however this one has fractions written differently at times and not as easy to read. Also seems like it may have skipped a step at the end. Finally, I also tried to solve this problem by making Umaima = 3t and having Tiffany be t. (as my starting point). Could you not solve this problem this way as well? If so, how? Why is forcing a fraction better?
