Q. Simplify. Express your answer as a single fraction in simplest form. 2c5−3d
Identify LCD: Identify the least common denominator (LCD) for the fractions.The denominators are 2 and 3, so the LCD is 2×3=6.
Rewrite fractions: Rewrite each fraction with the common denominator of 6. For the first fraction, multiply both the numerator and the denominator by 3 to get 63c5. For the second fraction, multiply both the numerator and the denominator by 2 to get 62d.
Combine fractions: Combine the fractions over the common denominator.(63c5−62d=63c5−2d)
Check for simplification: Check if the numerator can be simplified further.The terms in the numerator, 3c5 and 2d, do not have common factors other than 1, so the numerator cannot be simplified further.
