Answer 2

To solve the expression "-9 3/7 : (-7 6/7) : 0.04," we need to follow the order of operations (PEMDAS/BODMAS) and simplify step by step.

Step 1: Convert mixed numbers to improper fractions: -9 3/7 becomes -(97+3)/7 = -66/7 -7 6/7 becomes -(77+6)/7 = -55/7

Step 2: Perform the division: -66/7 : -55/7 = (-66/7) / (-55/7) = (-66/7) * (-7/55)

Step 3: Simplify the expression by canceling out common factors: (-66/7) * (-7/55) = (-66 * -7) / (7 * 55) = 462/385

Step 4: Divide by 0.04: (462/385) : 0.04 = (462/385) / (0.04) = (462/385) * (1/0.04)

Step 5: Simplify the expression: (462/385) * (1/0.04) = (462/385) * (25/1) = (462 * 25) / (385 * 1)

Step 6: Calculate the final result: (462 * 25) / (385 * 1) = 11,550 / 385 = 30

Therefore, the value of the expression "-9 3/7 : (-7 6/7) : 0.04" is 30.
