Khali and Juan are using ribbon to decorate their art project. The ratio of the length of Khali’s ribbon to the length of Juan’s ribbon is 8:5. If Khali used a total of 72 cm of ribbon, how much did Juan use?

45 cm

Step-by-step explanation:

First, you want to clarify the ratio:

Khali    =    8 cm   =     72 cm

Juan     =    5 cm   =      x cm

To find the missing variable, cross multiply and simplify for x:

8x = 72(5)

8x = 360

x = 45

So, Juan used 45 cm of ribbon if Khali used 72 cm.
