Which of the two painters above can team up to paint the whole room in 3 hours?

Answer:
[tex]\displaystyle Mary\:and\:Neil[/tex]
Step-by-step explanation:
[tex]\displaystyle 2 = \frac{7\frac{1}{2}}{3\frac{3}{4}}[/tex]
Two hours is much closer up three hours, so either way, they would still paint the room in time.
I am joyous to assist you anytime.
