Answer: You would need 5 men to paint a room in 3 hours
YWW :)
You would need to turn 4 4/9 and 2 7/9 into mix numbers. This would leave you with 50/9 - 25/9. Since the denominators are the same you just need to subtract the numerators 50 - 25 = 25. So the answer is 25/9
If I understand correctly, you went wrong because you solved for Y instead of M, like the question dictates.
