mr. Dagondon has twenty pieces of lumber that were all of the same length. If each piece of lumber was 3 1/5 inches long and he put then side by side, what would be the total length of all pieces together?

Respuesta :

We have the following:

the first thing is to pass the mixed number to an improper fraction

[tex]3\frac{1}{5}=\frac{15+1}{5}=\frac{16}{5}[/tex]

to calculate the sum of all, we must multiply by 20 (the number of total pieces) by the length

[tex]\frac{16}{5}\cdot20=64[/tex]

The total length is 64 inches
