• 2. Simplfy
  b - [b -(a+b) - {b - (b - a+b)} + 2a]

  1. a
  2. 2a
  3. 4a
  4. 0

  Answer And Explanation

  Answer: Option D

  Explanation:

  b-[b-(a+b)-{b-(b-a+b)}+2a]
  =b-[b-a-b-{b-(2b-a)}+2a]
  =b-[-a-{b-2b+a}+2a]
  =b-[-a-{-b+a}+2a]
  =b-[-a+b-a+2a]
  =b-[-2a+b+2a]
  =b-b
  =0

• 7. \begin{aligned}
  (3\frac{1}{4}\div \{1\frac{1}{4} - \frac{1}{2}(2\frac{1}{2} - \overline {\frac{1}{4} - \frac{1}{6}} ) \} )

  \overline{\frac{1}{4}-\frac{1}{6}}
  \end{aligned}
  So their sign will be changed from - to + as
  \begin{aligned}
  \frac{1}{4}+\frac{1}{6}
  \end{aligned}
