Answer:

Step-by-step explanation:

1/4

Step-by-step explanation:

First, add the terms within parenthesis:

1

+

1

8

)

1

2

2

8

Next, reduce the second term:

1

(

(

)

(

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

(

(

Now we can subtract the terms to obtain the final answer:

Answer:

1/4 or 0.25

Step-by-step explanation:

1/2 - (1/8 + 1/8)

= 1/2 + 2/8

= 4/8 - 2/8 (LCM)

= 2/8

= 1/4

= 0.25
