Changing Percent to Decimal

The question reads,

	"In a survey of 270 grade 9 students, 58 percent liked rock music. 
How many did not like rock music?"

I have tried to figure it out by making the 58 percent into a 
decimal (.58).  Is that right?

Yes, that will work.  Here's one way to do this problem:

.58 * 270 = number who like rock music

270 - number who liked rock music = number who DID NOT like rock 
music.

Does this make sense?
