I tried doing this problem several times in several different ways. I first attempted to split the 10 on the right side into its factors of 2 and 5. I also split the 4 on the rights into its factors of 2x2. However, I was clueless as to how I could combine the fractions, so just ended up guessing A and got it wrong. Please help.
