This is suppose to be solved using the multiplication principle. If possible please show me not just the answer but how you came up with it so I understand how to do these problems. Thank you

**(144)**(-x/9)=**(144)**(1/16)

16(-x) = 9(1)

-16x = 9

x = /9/16

you could just 'cross-multiply' to get the same result faster:

(-x)(16) = 1(9)

x = -9/16

In general find the lowest common denominator of your fractions, and multiply each term by that.

This will guarantee that all your denominators will cancel, and your fractions will disappear.
