Q. Simplify. Express your answer as a single fraction in simplest form. 25−5bc
Identify Common Denominator: Identify the common denominator for the fractions25 and 5bc. To combine these fractions, we need a common denominator. The least common denominator (LCD) for 2 and 5 is 10.
Rewrite with Common Denominator: Rewrite each fraction with the common denominator of 10. For the first fraction, 25, we multiply the numerator and denominator by 5 to get (2×55×5)=1025. For the second fraction, 5bc, we multiply the numerator and denominator by 2 to get (5×2bc×2)=102bc.
Subtract Fractions: Subtract the second fraction from the first fraction using the common denominator.Now we have (1025)−(102bc). Since the denominators are the same, we can subtract the numerators directly.1025−102bc=1025−2bc
Simplify Expression: Simplify the expression, if possible.The expression (25−2bc)/10 is already in its simplest form because 25 and 2bc do not have any common factors other than 1, and the denominator cannot be reduced further.
