Answer 2

To solve the given expression, let's break it down step by step:

-5 + 2/3 ÷ 4 + 1/4 - 5 + 1/3 ÷ 7/8

First, let's simplify the division operations:

2/3 ÷ 4 = 2/3 × 1/4 = 2/12 = 1/6

1/3 ÷ 7/8 = 1/3 × 8/7 = 8/21

Now, let's substitute the simplified values back into the expression:

-5 + 1/6 + 1/4 - 5 + 8/21

Next, let's find a common denominator for the fractions:

The common denominator for 6, 4, and 21 is 84.

Converting the fractions to have a denominator of 84:

-5 × 84/84 = -420/84

1/6 × 14/14 = 14/84

1/4 × 21/21 = 21/84

-5 × 84/84 = -420/84

8/21 × 4/4 = 32/84

Now, let's substitute the converted fractions back into the expression:

-420/84 + 14/84 + 21/84 - 420/84 + 32/84

Combining the fractions:

(-420 + 14 + 21 - 420 + 32)/84

Simplifying the numerator:

-773/84

Therefore, the solution to the given expression is -773/84.
