Answer 2

To solve this expression, we'll break it down step by step following the order of operations (PEMDAS/BODMAS: Parentheses/Brackets, Exponents/Orders, Multiplication and Division, Addition and Subtraction).

Here's your expression:

((-50 2/5 ÷ (-5, 6) + 6, 4) ÷ (-1 2/5))

1. Start by dealing with the innermost parentheses:

   -5, 6 is equivalent to -5.6

So, the expression becomes:

((-50 2/5 ÷ -5.6 + 6, 4) ÷ (-1 2/5))

2. Now, deal with the division and addition/subtraction from left to right:

   -50 2/5 ÷ -5.6 = (-50 2/5) / (-5.6)

To simplify this, convert the mixed numbers to improper fractions:

-50 2/5 = -252/5

Now, perform the division:

(-252/5) / (-5.6)

To divide fractions, multiply by the reciprocal of the divisor:

(-252/5) * (-1/5.6)

Now, multiply the fractions:

(252/5) * (1/5.6)

3. Next, add 6.4 to the result from step 2:

   (252/5) * (1/5.6) + 6.4

4. Finally, divide the result from step 3 by -1 2/5, again converting the mixed number to an improper fraction:

   -1 2/5 = -7/5

Now, divide the result from step 3 by -7/5:

[(252/5) * (1/5.6) + 6.4] / (-7/5)

To divide by a fraction, multiply by its reciprocal:

[(252/5) * (1/5.6) + 6.4] * (-5/7)

Now, calculate this expression:

[(252/5) * (1/5.6) + 6.4] * (-5/7)

This will give you the final result. Calculate it step by step to get the exact value.
