What is 0.5 divided by 12.5
lisabon 2012 [21]

Answer:

<em>0</em><em>.</em><em>04</em><em> </em><em>o</em><em>r</em><em> </em><em>4</em><em>%</em>

Step-by-step explanation:

<em>-A fraction consists of two numbers and a fraction bar: 0.5/12.5</em>

<em>- The number above the bar is the numerator: 0.5</em>

<em>The number below the bar is the denominator: 12.5</em>

<em>-Divide the numerator by the denominator to get fraction's value: Val = 0.5 ÷ 12.5</em>

<em>Calculate fraction's value.</em>

<em>Divide the numerator by the denominator to get fraction's value:</em><em> </em>

<em>0.5 ÷ 12.5 </em>

<em>=</em><em> </em><em>0.04</em>

<h3><em> </em><em>Calculate the percent value:</em></h3>

<em>Note:100/100 = 100 ÷ 100 = 100% = 1Multiply a number by the fraction 100/100,... and its value doesn't change.0.04 =</em>

<em>=</em><em> </em><em>0.04 × 100/100 </em>

<em>=</em><em> </em><em>(0.04 × 100)/100 </em>

<em>=</em><em> </em><em>4/100 </em>

<em>=</em><em> </em><em>4%;</em>

<h3><em>In other words:</em></h3>

<em>1) Calculate fraction's value.</em>

<em>2) Multiply that number by 100.</em>

<em>3) Add the percent sign % to it.</em>

<em>Answer:</em>

<em>0.5</em><em>÷</em><em>1</em><em>2.5 = 4%</em>
