Answer 2

Let's break down the equation step by step:

1. Start with the left-hand side of the equation:

   -(-8.5 - 3 целых 3/2 + 6 целых 4/15) - 1/5

   First, simplify the mixed fractions: -(-8.5 - (3 * 1.5) + (6 * 4/15)) - 1/5 -(-8.5 - 4.5 + 1.6) - 1/5

   Now, combine the numbers: -(-11.4) - 1/5

   Since you have a negative sign in front of a negative number, it becomes positive: 11.4 - 1/5

   To add the fraction and the decimal, you can convert the decimal to a fraction with a common denominator:

   11.4 = 114/10

   So, the equation becomes: (114/10) - (1/5)

   Now, find a common denominator (which is 10): (114 - 2) / 10 112/10

   Reduce the fraction: 56/5

2. Move on to the right-hand side of the equation:

   (4/8 - 5 целых 3/14) - (-4 целых 3/25 + 4 целых 8/35)

   First, simplify the mixed fractions on the right side: (4/8 - (5 * 3/14)) - (-(4 * 3/25) + (4 * 8/35))

   Reduce fractions and multiply: (1/2 - 15/14) - (-12/25 + 32/35)

   Now, find a common denominator for each subtraction: (7/14 - 15/14) - (-12/25 + 32/35)

   Perform the subtractions: (-8/14) - (-120/250 + 224/350)

   Simplify fractions: (-4/7) - (-48/100 + 64/100)

   Continue simplifying: (-4/7) - (16/100)

   Reduce the fraction on the right side: (-4/7) - (4/25)

3. Now, subtract the right-hand side from the left-hand side:

   (56/5) - (-4/7 + 4/25)

   Find a common denominator: (56/5) - (-100/175 + 28/175)

   Combine fractions: (56/5) - (-72/175)

   To subtract fractions, you'll need to find a common denominator: (56/5) - (-72/175) = (56/5) + (72/175)

   Find a common denominator: (560/35) + (72/175)

   Now, convert the first fraction to have a denominator of 175: (800/175) + (72/175)

   Combine the fractions: (800 + 72) / 175 872/175

So, the final result is:

872/175
