Definition: Unlike Fraction Addition |
|
Fractions that have unequal denominators are known as unlike fractions. The two fractions stem from \$p/q\$ and \$r/s\$, and their denominators q and s are equal (i.e.,q ≠ s), so they are unlike fractions. Unlike fractions, make the denominators the same first and then add them. |

Explanation: The numbers \$4/3, 12, 18, 35/40, and 20/30\$ are unlike fractions. |
