How to add and subtract rational numbers?

When we add or subtract rational numbers that have the same denominator, we add or subtract only the numerators. The denominators stay the same.
When we add or subtract rational numbers with unlike denominators, we need to change the rational numbers to equivalent rational numbers that have the same denominators, before we find the sum or difference.
