Answer:
liquid A will evaporate at 25/18 cups per hour.
liquid B is 8/3 cups per hour.
Step-by-step explanation:
To calculate the unit rate you need to calculate per hour, remember that unit rate always uses as numerator number 1.
[tex]\frac{\frac{5}{9} }{\frac{2}{5} } \\\frac{5*5}{2*9}=\frac{25}{18}[/tex]
So the liquid A will evaporate at 25/18 cups per hour.
And the liquid B:
[tex]\frac{\frac{8}{9} }{\frac{1}{3} } \\\frac{3*8}{1*9}=\frac{24}{9}\\\frac{8}{3}[/tex]
So the evaporation rate of liquid B is 8/3 cups per hour.
