9-104.

For help solving proportions, refer to the Math Notes box below.

We can choose cross multiplication, which is Strategy 2 in the Math Notes box above.

Your expression would then look something like this: 18*x* = (12)(12) Can you find the value of *x* now?

How many 18's are in 144? You can figure this out by dividing 144 by 18.

Which strategy do you like to use more? Both will work here, so remember to show your work!

The value of *p* is 27.5.
