Question: `q001. Note that there are five questions in this set.

If y is proportional to x, and if y = 9 when x = 12, then what is the value of y when x = 32?

YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY

Your solution:

32/12=2.67

9*2.67

=24

Question: `q002. If y is proportional to the square of x, and y = 8 when x = 12, then what is the value of y when x = 9?

YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY

Your solution:

4.5

*********************************************

Question: `q003. If y is inversely proportional to x and if y = 120 when x = 200, when what is the value of y when x = 500?
