Hi there!

nearest percentage=64%

<em><u>1.Subtract starting value and final value:</u></em>

<em><u /></em>1599-579=1020<em><u /></em>

<em><u>2.Divide it by the starting value:</u></em>

<em><u /></em>1020*1599= 0.6378986866791744840525328330206378986<em><u /></em>

<em><u>3.Multiply the term by 100:</u></em>

<em><u /></em>0.6378986866791744840525328330206378986<em><u>·</u></em>100= 63.78986866791744840525328330206378986<em><u /></em>

<em><u>4.Round the term:</u></em>

<em><u /></em>63.78986866791744840525328330206378986=64<em><u /></em>
