<h3>
1.) Find the LCF of 6 and 4:
</h3>
<em> - We do this because in order to add these, they must have the same denominator. So you must find the LCF, (Least Common Factor) of 6 and 4.</em>
<em />
<h3>
2.) Convert the fractions to have the same denominator:
</h3>
<em> - </em>
<em> changes to </em>
<em> by multiplying the numerator and denominator by 2. And </em>
<em> changes to </em>
<em> because you multiply the numerator and denominator by 3. </em>
<em></em>
<h3>
3.) Add the numerators:
</h3>
<em> - Since both fractions have the same denominator all you have to do is add the numerators together. </em>
