Question

DomyTom needs to buy a wood board long enough to cut into 4 pieces,each of which needs to measure 8 5/7inches. Estimate to the nearest inchhow long of a board Tom needs to buy.A.32 inchesB. 40 inchesC. 36 inchesD.9 inches

Answer 1

The wood board will be cut into 4 pieces

Lenght of each is

`8(5)/(7)\text{ inches }`

Then we simplify the fraction above

`8(5)/(7)=(61)/(7)inches\text{ }`

`\begin{gathered} (61)/(7)=8.9\text{ } \\ \text{Which is estimated as } \\ 9\text{inches} \end{gathered}`

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

`4*9=36\text{ inches }`

Tom needs to buy a wood board of 36 inches

Option C is Right
