Question

john needs to cut three strips of wood 11 3/5 inches, 15 1/5 inches, and 9 2/5 inches long. He has a strip that is 48 inches long.How long will the leftover piece be after he cuts what he wants?

Answer 1

11 4/5 because when you add 11 3/5, 15 1/5, and 9 2/5 together you get 36 1/5 and since you are cutting that much off you subtract that from 48 which is 11 4/5.

Answer 2

Answer:

$11\frac{4}{5}$ inches

Step-by-step explanation:

John has a strip of wood that is 48 inches long.

He needs to cut three strips of wood that is

$11\frac{3}{5}$ inches,  $15\frac{1}{5}$ inches and  $9\frac{2}{5}$ inches long.

The total length of strips he needed =  $11\frac{3}{5}$ +  $15\frac{1}{5}$ +  $9\frac{2}{5}$

=  $\frac{58}{5}$ +  $\frac{76}{5}$ +  $\frac{47}{5}$

=  $\frac{58+76+47}{5}$

=  $\frac{181}{5}$

=  $36\frac{1}{5}$

He used  $36\frac{1}{5}$ inches to cut three strips.

Now the leftover piece = 48 -  $36\frac{1}{5}$

                                      = 48 -  $\frac{181}{5}$

                                      =  $\frac{240-181}{5}$

                                      =  $\frac{59}{5}$

                                      =  $11\frac{4}{5}$

The leftover piece would be  $11\frac{4}{5}$ inches
