Adding/Subtracting Fractions

<p><span style="font-size:22px"><a href="https://www.prepswift.com/quizzes/quiz/prepswift-addingsubtracting-fractions" target="_blank">Adding/Subtracting Fractions Exercise</a></span></p><p>To <strong><span style="color:#27ae60;">Add Fractions</span></strong>, follow these steps:</p> <ul> <li>Check to see if the denominator&nbsp;of each fraction is the same. If so, adding fractions is easy. Simply add the numerators and keep the same denominator.</li> </ul> <p>$$\frac{3}{7} + \frac{2}{7} = \frac{5}{7}$$</p> <ul> <li>However, if the two (or more) denominators are not the same, you have to make them the same by finding the Least Common Multiple of the denominators. See the example below:</li> </ul> <p>$$\frac{5}{8} + \frac{1}{12} = \left(\frac{3}{3} \right)\left(\frac{5}{8}\right) + \left(\frac{2}{2} \right)\left(\frac{1}{12}\right) = \frac{15}{24} + \frac{2}{24} = \frac{17}{24}$$&nbsp;</p> <p>You follow the exact same process for <strong><span style="color:#27ae60;">Subtracting Fractions</span></strong>, except this time there is a minus sign in the middle and you have to subtract the numerators to the right from the numerator on the left.</p>
