So what this is asking is how many minutes does he spend texting each day. Well since he only spends 60 minutes texting each day, and 90% of the 60 minutes spent is texting, so how many minutes does he spend texting? So what your trying to find is 90% of 60 minutes. So the problem is 90%, which is the same as .90,times 60. What is .90 times 60? Do that problem and you will get the amount of minutes he spends texting each day.
