For this case we have the following fraction:
[tex]\frac {4} {14}[/tex]
If we divide the numerator and denominator by 2 we have:
[tex]\frac {\frac {4} {2}} {\frac {14} {2}} =\\\frac {2} {7}[/tex]
Now, if we multiply the numerator and denominator by 3 we have:
[tex]\frac {2 * 3} {7 * 3} =\\\frac {6} {21}[/tex]
Finally, we have that an equivalent expression is [tex]\frac {6} {21}[/tex]
Answer:
[tex]\frac {4} {14}[/tex] is equivalent to[tex]\frac {6} {21}[/tex]
