Here is the description of all the attributes of this tag −

• linethickness − to specify the stroke width of the fraction bar. values are measured in px, pt, em etc.

• numalign − to specify alignment of numerator. values are left, right or center.

• denomalign − to specify alignment of denominator. values are left, right or center.

Example

Let's draw a simple fraction for 1/x.

<math xmlns = "http://www.w3.org/1998/Math/MathML">
   <mfrac>
      <mn>1</mn>
      <mi>x</mi>
   </mfrac>
</math>

Output

Let's build a complex fraction.

<math xmlns = "http://www.w3.org/1998/Math/MathML">
   <mfrac linethickness = '3px'>
      <mfrac bevelled = 'true'>
         <mn>1</mn>
         <mi>x</mi>
      </mfrac>
      
      <mrow>
         <mi>y</mi>
         <mo>-</mo>
         <mn>2</mn>
      </mrow>
   </mfrac>
</math>
