For this case we must indicate a form to determine if the following expressions are equal:
[tex]\frac {3} {12}\ and\ \frac {1} {4}[/tex]
It is observed that if we multiply the numerator and denominator of the second fraction by "3" we obtain the first fraction:
[tex]\frac {1 * 3} {4 * 3} = \frac {3} {12}[/tex]
Similarly, if we divide the numerator and denominator of the first fraction between "3" we obtain the second fraction.
[tex]\frac {\frac {3} {3}} {\frac {12} {3}} = \frac {1} {4}[/tex]
ANswer:
Divide the numerator and denominator of the first fraction between "3" or
Multiply the numerator and denominator of the second fraction by "3"
