Answer:
(a)-2 (b)-24 (c)-4 (d)-13/24
Explanation:
Part A
First, we open the bracket. Take note that:
• - x - = +
,• - x + = -
So:
[tex]9+(-11)=9-11=-2[/tex]Part B
[tex]\begin{gathered} -16+(-8)=-16-8 \\ =-24 \end{gathered}[/tex]Part C
[tex]\begin{gathered} -6+2=2-6 \\ =-4 \end{gathered}[/tex]Part D
[tex]\frac{1}{8}+(-\frac{2}{3})=\frac{1}{8}-\frac{2}{3}[/tex]Next, we take the lowest common multiple of the denominators: 8 and 3
L.C.M. of 8 and 3 = 24
We then have:
[tex]\begin{gathered} \frac{3-2(8)}{24}=\frac{3-16}{24} \\ =-\frac{13}{24} \end{gathered}[/tex]
