Answer 2

To solve the expression (1 1/35:4/5 - 1 8/35) * 3 1/5, you'll want to break it down step by step.

1. Start by simplifying the expression within the parentheses: 1 1/35:4/5 - 1 8/35

   To subtract mixed numbers, you need to find a common denominator. The common denominator for 5 and 35 is 35. Convert the fractions to have a denominator of 35:

   (1 * 7/7 + 1/35) - (1 * 8/8 + 8/35)

   Now, you have:

   (7/7 + 1/35) - (8/8 + 8/35)

   Simplify further:

   (1 + 1/35) - (1 + 8/35)

   Now, subtract:

   1 + 1/35 - 1 - 8/35

   Combine like terms:

   (1 - 1) + (1/35 - 8/35)

   0 + (-7/35)

   -7/35 is equivalent to -1/5.

2. Now, you have the simplified expression: (-1/5) * 3 1/5.

   To multiply a fraction by a mixed number, convert the mixed number to an improper fraction:

   3 1/5 = (5 * 3 + 1)/5 = 16/5

3. Multiply the fractions:

   (-1/5) * (16/5)

   To multiply fractions, simply multiply the numerators together and the denominators together:

   (-1 * 16) / (5 * 5) = -16/25

So, the result of the expression (1 1/35:4/5 - 1 8/35) * 3 1/5 is -16/25.
