Additional wire of 26 7/20 feet, in the form of a mixed fraction, is required to complete the job.
A mixed fraction is represented by both its quotient and remainder. An amalgam of a whole number and a legal fraction is a mixed fraction.
Max has total 6*9 2/5feet of wire, that is, 282/5 feet of wire.
Fred has total 7*16 3/4 feet of wire, that is, 469/4 feet of wire.
The total amount of wire required=200 feet
The total amount of wire available=282/5+469/4
