Answer 1

Answer:

• - 7/40  

------------------------------

Given expression:

• 1/4 + 1/5 + (-3/4 + 1/8)

Simplify it in below steps:

• 1/4 + 1/5 + (-3/4 + 1/8) =               Solve the parenthesis
• 1/4 + 1/5 + (-6/8 + 1/8) =               Bring to common denominator of 8
• 1/4 + 1/5 + (-5/8) =
• 1/4 + 1/5 - 5/8 =                            Open the parenthesis
• 10/40 + 8/40 - 25/40 =               Bring to common denominator of 40
• (18 - 25) / 40 =                             Simplify
• - 7/40                                           Answer

Answer 2

Answer:

-7/40 (None of the above)

Step-by-step explanation:

Given problem,

→ (1/4) + (1/5) + ((-3/4) + (1/8))

Let's simplify the problem,

→ (1/4) + (1/5) + ((-3/4) + (1/8))

→ ((5/20) + (4/20)) + ((-6/8) + (1/8))

→ ((5 + 4)/20) + ((-6 + 1)/8)

→ (9/20) + (-5/8)

→ (18/40) + (-25/40)

→ (18 +(-25))/40

→ (18 - 25)/40

→ -7/40

Hence, the answer is -7/40.
