Question

A carpenter has a board that is 8 feet long. He cuts off two pieces. One piece is 3 1/2 feet long and the other is 2 1/3 feet long. How much of the board is left?

Answer 1

8-{7/2+7/3} is 8-(35/6) is 13/2 isequal to 6.5

Answer 2

Answer:

2.16 feet

Step-by-step explanation:

A carpenter has board that is 8 feet long.

He cuts one piece of length = $3\frac{1}{2} =\frac{7}{2}$

So, length of remaining board = $8-\frac{7}{2}$

                                                  = $\frac{16-7}{2}$

                                                  = $\frac{9}{2}$

So, remaining wood is  9/2 feet long

He cut other piece of length= $2\frac{1}{3} =\frac{7}{3}$

So, length of remaining board = $\frac{9}{2}-\frac{7}{3}$

                                                  = $\frac{27-14}{6}$

                                                  = $\frac{13}{6}$

So, remaining board is of length  $\frac{13}{6}=2.16 feet$

Hence 2.16 feet board is left .
