Answer:
17 hours
take $192 and divide it by 12 so you know how much they make per hour
$192 / 12 = 16
then you're going to take $272 and divide it by what you know now - how much they make per hour (this will get you how many hours they worked)
$272 / 16 = 17
It is less than 5.2, simply because the number is negative.
1 3/9 but if reduce to lowest term than 1 1/3
