spayn [35]

<em><u>ANSWER</u></em>

<em>Since </em><em>probably </em><em>part </em><em>of </em><em>the</em><em> </em><em>pie </em><em>was </em><em>already </em><em>eaten </em><em>therefore </em><em>we </em><em>find </em><em>the </em><em>fration </em><em>of </em><em>the </em><em>pie </em><em>in </em><em>the </em><em>beginning</em><em> </em><em>which </em><em>is</em>

<em>=</em><em> </em><em>1</em><em> </em>

<em>=</em><em> </em><em>5</em><em>/</em><em>5</em>

<em><u>Fraction </u></em><em><u>William </u></em><em><u>ate;</u></em>

<em>=</em><em> </em><em>3</em><em>/</em><em>4</em><em> </em><em> </em><em>of </em><em>1</em>

<em>=</em><em> </em><em>3</em><em>/</em><em>4</em><em> </em><em>of </em><em>5</em><em>/</em><em>5</em>

<em>=</em><em> </em><em>3</em><em>/</em><em>4</em><em> </em><em>×</em><em> </em><em>5</em><em>/</em><em>5</em>

<em>=</em><em> </em><em>3</em><em>/</em><em>4</em>

<em> </em>

<em><u>CONCLUSION</u></em>

A fraction is a part of a whole so no matter how the fraction would increase or decrease the part William ate will remain the same
