An experiment measured the evaporation rates of two liquids, liquid a and liquid b, at a certain temperature and pressure. after 2/5 hour, 5/9 cup of liquid a evaporated. after 1/3 hour, 8/9 cup of liquid b evaporated. what is the unit rate for evaporation liquid a. what is the unit rate for evaporation liquid b

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.

So the liquid A will evaporate at 25/18 cups per hour.

And the liquid B:

So the evaporation rate of liquid B is 8/3 cups per hour.

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
