Answer 2

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

1. Convert the mixed number to an improper fraction: 2 1/5 = 11/5

2. Perform the multiplication and subtraction operations first: 6/11 × 11/5 - 2 × (-0.1)

   Multiplying fractions: (6/11) × (11/5) = (6 × 11) / (11 × 5) = 66/55

   Multiplying a number by a negative value is the same as multiplying it by -1 and then multiplying by the positive value: 2 × (-0.1) = -2 × 0.1 = -0.2

3. Perform the final subtraction: 66/55 - 0.2

   To subtract fractions, we need a common denominator: The common denominator of 55 and 1 is 55, so we need to convert 0.2 to a fraction with a denominator of 55. 0.2 = 2/10 = 11/55 (multiply numerator and denominator by 11)

   Now we can subtract the fractions: 66/55 - 11/55 = (66 - 11) / 55 = 55/55 = 1

Therefore, 6/11 × (2 1/5) - 2 × (-0.1) equals 1.
