The problem states that "5 to 8 is as 15 to w." I'm having some trouble solving this because I am unsure of what the problem is asking me to do. Some help would be appreciated. Thank you! :)

The problem is a proportion and is asking you to find the value of w.
5/8 = 15/w
Cross multiply and solve for w
5/8 = 15/w
5w = 120
w = 24
5 is to 8 as 15 is to 24
