Question

A carpenter had a piece of wood that was 15 feet in length. If he needs only 10 and five-twelfths feet of wood, how much wood should be cut?

Answer 1

Given that,

Length of piece of wood is 15 feet

A carpenter needs 10 and five-twelfths feet of wood.

To find,

How much wood should be cut?

Solution,

Total length of piece is 15 feet

He needs $10\dfrac{5}{12}$ part of wood

So,

Wood he should cut = total length - needed piece of wood

Wood he should cut =  $15-10\dfrac{5}{12}$

Wood he should cut = $\dfrac{55}{12}=4\dfrac{7}{12}\ \text{feet}$

So, he must cut $4\dfrac{7}{12}\ \text{feet}$ of wood.
