Math Is Fun Forum

I have several couple averages  I need help with please.

1.    If a person  who works as a casual has a wage of  $655.58 in a period of 28 days and has only worked 32 hours how would i work that out the average please?

2.   If a person works an earns $3092.53 over 112 days  but only worked  124 hours how do i work that out average please?

Or would i have to base the average on a yearly time frame.  But then i have to consider that this person would not work nor get paid leave.  The unpad leave would be 12 weeks of no work or pay. 

So what would be the average pay per week for that person?

Hope you can help   

Thanks heaps
