Question

To wire the entire new addition, max and fred have 6 rolls of wire with 9 2/5 feet per roll and 7 rolls of wire with 16 3/4 feet per roll. how many feet of additional wire do they need in order to complete the job if it requires 200 feet of wire? write the result as a mixed number.

Answer 1

Additional wire of  $26\frac{7}{20}$  feet, in the form of a mixed fraction, is required to complete the job.

What is the length of additional wire required, in the form of a mixed fraction?

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 $6*9\frac{2}{5}$ feet of wire, that is, 282/5 feet of wire.

Fred has total $7*16\frac{3}{4}$ feet of wire, that is, 469/4 feet of wire.

The total amount of wire required=200 feet

The total amount of wire available=$\frac{282}{5}+\frac{469}{4}$

                                                  $=\frac{3473}{20}$

An additional amount of wire is required=$200-\frac{3473}{20}$

                                                          =$\frac{4000-3473}{20}$

                                                          =$\frac{527}{20}$

Thus, the additional amount of wire required is expressed as a mixed fraction=$26\frac{7}{20}$ of feet.
