Q. Which of the following is equivalent to (a+6c)(2a+62c) \frac{\left(\frac{a+6}{c}\right)}{\left(\frac{2 a+6}{2 c}\right)} ?\newlineChoose 11 answer:\newline(A) c2 \frac{c}{2} \newline(B) a+6a+3 \frac{a+6}{a+3} \newline(C) a+62(a+3) \frac{a+6}{2(a+3)} \newline(D) 11
  1. Write Expression: Write down the given expression and identify the structure.\newlineThe given expression is a complex fractions" target="_blank" class="backlink">fraction, which means it is a fraction where the numerator and the denominator are themselves fractions.\newlineThe expression is: (a+6c)(2a+62c)\frac{\left(\frac{a+6}{c}\right)}{\left(\frac{2a+6}{2c}\right)}
  2. Identify Structure: Simplify the complex fraction by multiplying the numerator and the denominator by the reciprocal of the denominator.\newlineTo simplify a complex fraction, we can multiply the numerator and the denominator by the reciprocal of the denominator of the complex fraction.\newlineReciprocal of (2a+62c)\left(\frac{2a+6}{2c}\right) is 2c2a+6\frac{2c}{2a+6}.\newlineSo, we have: (a+6c)×2c2a+6\left(\frac{a+6}{c}\right) \times \frac{2c}{2a+6}
  3. Simplify by Multiplying: Perform the multiplication.\newlineNow, multiply the numerators together and the denominators together.\newline(a+6)×(2c)c×(2a+6)\frac{(a+6) \times (2c)}{c \times (2a+6)}
  4. Perform Multiplication: Simplify the expression by canceling out common factors.\newlineWe can cancel out the 'c' from the numerator and the denominator.\newline(2(a+6))/(2a+6)(2(a+6)) / (2a+6)
  5. Cancel Common Factors: Further simplify the expression.\newlineSince there is a common factor of 22 in the numerator, we can cancel it out with the 22 in the denominator.\newline(a+6)/(a+3)(a+6) / (a+3)
  6. Further Simplify: Match the simplified expression with the given options.\newlineThe simplified expression (a+6)/(a+3)(a+6) / (a+3) matches with option (B).
