Homework Help: chemistry

Posted by risha on Saturday, October 23, 2010 at 5:45pm.

A radio station's channel, such as 100.7 FM or 92.3 FM, is actually its frequency in megahertz (MHz), where 1 MHz =10^6 Hz}. Calculate the broadcast wavelength of the radio station 98.70 FM.

can someone please explain this question for me, i tried several times and all 3 of my answers were wrong, i don't understand how to approach this problem.
my answers i got were 30, 300 and 3*10^-7 which were all wrong.
i understand you have to use the c=f*wavelength formula though
