Answer:

45 cm

Step-by-step explanation:

It is given that,

The ratio of the length of Khali's ribbon to the length of Juan's ribbon is 8:5.

We need to find the length of ribbon used by Juan if Khali used a total of 72 cm of ribbon. ATQ,

$\dfrac{K}{J}=\dfrac{8}{5}\\\\\dfrac{8}{5}=\dfrac{72}{J}\\\\J=\dfrac{5\times 72}{8}\\\\J=45\ cm$

So, Juan uses 45 cm of the ribbon.
