Find LCM of denominators: Find the least common multiple (LCM) of the denominators 4 and 5. The LCM is 20.
Make denominators the same: Make the denominators the same by multiplying the first fraction by 5 and the second fraction by 4. This gives us 205u4−204tu.
Simplify the expression: Simplify the expression by subtracting the numerators since the denominators are the same. The final simplified expression is (5u4−4tu)/20.
