In adding and subtracting fractions with unlike denominators, you have to get a least common denominator which is exactly like the least common multiple it just so happens to be in the denominator.

Adding and subtracting algebraic fractions is a similar process to adding and subtracting normal fractions. The denominators of each fraction are different, \(3t\) and \(7t\), so a common denominator ...

Fractions, often perceived as daunting, become manageable with the right approach. Addition and subtraction require finding a common denominator, while multiplication involves directly multiplying ...
