Answer 2

Given:

Donny has a 10-foot board.

length of the first shelf$=4 feet 7 inches$

length of the second shelf$=3 feet 2 inches$

To find: length of the remaining piece of board.

Solution:

Understand that, In a foot there are 12 inches.

Therefore,

$\[10{\rm{ }}ft = 10 \times 12\]$

       $= 120$ inches

4 ft 7 inches $= 4(12) + 7$

                      $= 55$inches

3 ft 2 inches $= 3(12) + 2$

                     $= 36 + 2$

                     $= 38$ inches

Find the length of the remaining piece of wood.

$120 -55 -38 = 27$ inches

Convert 27 inches into feet and inches.

$1$ inch$=$$\[\frac{1}{{12}}\]$ feet

$\[\begin{array}{l} \Rightarrow 27inches = \frac{{27}}{{12}}\\ \Rightarrow 27inches = 2ft\,\,3\,inches\end{array}\]$

Hence, the length of the remaining piece of wood is 2 ft 3 inches.
