\( \Large 5\frac{1}{2}+4\frac{1}{6}-x+2\frac{2}{3}=4\frac{1}{2} \)

A) \( \Large 2\frac{5}{6} \)
B) \( \Large 4\frac{5}{6} \)
C) \( \Large 7\frac{5}{6} \)
D) \( \Large 6\frac{5}{6} \)

Correct Answer:



C) \( \Large 7\frac{5}{6} \)

Description for Correct answer:
\( \Large 5\frac{1}{2}+4\frac{1}{6}-x+2\frac{2}{3}=4\frac{1}{2} \)

=\( \Large \frac{11}{2}+\frac{25}{6}-x+\frac{8}{3}=\frac{9}{2} \)

=\( \Large \frac{33+25+16}{6}-x=\frac{9}{2},\ \frac{74}{6}-x=\frac{9}{2} \)

\( \Large x = \frac{74}{6}-\frac{9}{2} \)

= \( \Large \frac{74-27}{6}=\frac{47}{6}= 7\frac{5}{6} \)
