Answer 2

To solve this arithmetic expression, you need to add the three given numbers together:

1. Convert the mixed fraction to an improper fraction: -5 3/7 = -(5*7 + 3)/7 = -38/7

2. Now, add the fractions: (1/4) + (-38/7) + (-0.0625)

3. Convert -0.0625 to a fraction: -0.0625 = -625/10000

4. Find a common denominator for the fractions, which is the least common multiple of 4 and 7, which is 28.

Now, let's put everything over a common denominator and add:

(1/4)(7/7) + (-38/7) + (-625/10000)(28/28) = 7/28 - 38/7 - 17500/280000 = 7/28 - 152/28 - 17500/280000 = -145/28 - 17500/280000

Now, let's further simplify the fractions:

-145/28 - 17500/280000 = (-7250 - 17500)/280000 = -24750/280000

This fraction can be further simplified by dividing both the numerator and denominator by their greatest common divisor, which is 1250:

-24750/280000 = -(24750/1250)/(280000/1250) = -19.8/224 = -99/1120

So, the result of the expression (1/4) + (-5 3/7) + (-0.0625) is approximately -99/1120.
