1. It went wrong because you are supposed to reciprocate the 2nd term, because of the Keep-Change-Flip rule. Therefore the correct answer is 1 because 2/5 • 3/1 = 6/5 or simply 1 1/5.
2. It went wrong because you are not supposed to reciprocate the 1st term, only the 2nd term. Therefore the correct answer is 3/4 • 5/2 = 15/8 or 1 7/8.
3. It went wrong because once again, you must reciprocate the 2nd term. Therefore the correct answer is 5/6 • 1/8 = 5/48
4. It went wrong at the last part, 6 • 6 is not 42, rather it s 36. So 5/36 is the correct answer.
