what is the process for solving the following question?

John is 72 inches tall and casts a 40 inch shadow.
A monument casts a 24 foot shadow. How tall is the monument?

5 answers

72/40 =h/24
so
h = 24 (72/40) feet
Change the inches to feet.

72 inches = 6 feet
40 inches = 3.333 feet

Set up a proportion and cross multiply.

6/3.333 = x/24
Thank you so much!
LOL
72/40 = 6/3.3333....
Ratio of height to shadow length could be in shoelace lengths as long as the same shoelace is used top and bottom.
