Answer:
Step-by-step explanation:
1/4
Step-by-step explanation:
First, add the terms within parenthesis:
1
2
−
(
1
8
+
1
8
)
⇒
1
2
−
2
8
Next, reduce the second term:
1
2
−
(
(
2
2
)
⋅
(
1
4
)
)
⇒
1
2
−
(
1
⋅
(
1
4
)
)
⇒
1
2
−
1
4
To get these two terms over a common denominator (in this case
4
) we need to multiple the first term by
(
2
2
)
:
1
2
−
1
4
⇒
(
(
2
2
)
⋅
(
1
2
)
)
−
1
4
=
2
4
−
1
4
Now we can subtract the terms to obtain the final answer:
2
4
−
1
4
⇒
2
−
1
4
⇒
1
4
