In reviewing Daniel's math homework, his teacher noticed he made a mistake. Instead of 26/73, he erroneously used 83/73 in his first calculation for 'w'. Now Daniel needs to correct his work. So initially, he has to add 26/73 and 53/77 to calculate 'w'. Then to find 'z', he needs to add 80/76 to 'w'. What will be his new final result for 'z' in simplified fraction form?
