2. Simplfy
b - [b -(a+b) - {b - (b - a+b)} + 2a]- a
- 2a
- 4a
- 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 -
3. 100 + 50 * 2 = ?
- 200
- 150
- 100
- 300

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}} ) \} )
\end{aligned}- 78
- 88
- 98
- 108
Answer And Explanation
Answer: Option A
Explanation:
Tip:
As you can see, there is bar over
\begin{aligned}
\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}
