Question

eddy drilled into a piece of wood and a joist to attach them if he drilled 3 inches and the wood was 1 1/3 inches thick how far did he drill into the joist

2 Answer

  • ¬†JD = 5/3 or 1 2/3 inches.
  • In order to find how far was drilled into the joist subtract the thickness of the wood from the total drilled and follow those steps

    Step 1

    Convert mixed number to an improper fraction

    [tex]1\frac{1}{3}\ in= \frac{1*3+1}{3}= \frac{4}{3}\ in[/tex]

    Step 2

    Subtract the thickness of the wood from the total drilled

    [tex]3-\frac{4}{3}= \frac{9}{3}- \frac{4}{3}= \frac{5}{3}\ in[/tex]

    Step 3

    Convert improper fraction to a mixed number

    [tex]\frac{5}{3}\ in=\frac{3}{3}+\frac{2}{3}=1+\frac{2}{3}=1\frac{2}{3}\ in[/tex]

    therefore

    the answer is

    [tex]1\frac{2}{3}\ in[/tex]
