Set up this proportion and cross multiply. Solve for x.

60/12 = x/4

What you're saying in this proportion is:

60 is to 12 as an unknown is to 4.

60/12 = x/4

12x = 240

Divide both sides of the equation by 12 to find the value of x.

You're very welcome.

I'm sorry, but I don't remember how to do your other math problem. I'm basically a social studies and English teacher.
