Q. Simplify. Express your answer as a single fraction in simplest form. 45−w5x2
Identify LCM: Identify the least common multiple (LCM) of the denominators 4 and w5x. Since 4 and w5x have no common factors other than 1, the LCM is simply their product, which is 4w5x.
Make denominators same: Make the denominators the same by multiplying the first fraction by w5x/w5x and the second fraction by 4/4. This gives us (5w5x)/(4w5x)−(8)/(4w5x).
Simplify expression: Simplify the expression by subtracting the numerators since the denominators are the same. The final simplified expression is (4w5x5w5x−8).
