Luna mixes 3/4 of orange juice and 3/8 of cranberry juice and then she gave mags 5/8 cup of juice and we have to turn it into an mixed number

1/2

Step-by-step explanation:

The question is for us to calculate the amount of juice that's left.

We are told that Luna mixes 3/4 of orange juice and 3/8 of cranberry juice. The amount of juice mixed will be:

= 3/4 + 3/8

= 6/8 + 3/8

= 9/8

= 1 1/8

We are then told that she gave Mags 5/8 cup of juice. The amount of juice that's then left will be:

= 1 1/8 - 5/8

= 4/8

= 1/2

1/2 cup of juice will be left

21

step-by-step explanation:

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.
