SOLUTION

The wood board will be cut into 4 pieces

Lenght of each is

[tex]8\frac{5}{7}\text{ inches }[/tex]

Then we simplify the fraction above

[tex]8\frac{5}{7}=\frac{61}{7}inches\text{ }[/tex]

[tex]\begin{gathered} \frac{61}{7}=8.9\text{ } \\ \text{Which is estimated as } \\ 9\text{inches} \end{gathered}[/tex]

Since there are 4 pieces, we then multiply the lenght of each

[tex]4\times9=36\text{ inches }[/tex]

Tom needs to buy a wood board of 36 inches
