Question

(-1 3/7+5 3/7-4)*(-1 1/7)=

Answer 1

1) - 10\7 + 38\7 = -10+38 \ 7 = 28\7 = 4

2) 4-4 =0

3) 0 * ( - 1  1\7) =0

Answer 2

Let's simplify the expression step by step:

Step 1: Add the fractions inside the parentheses: (-1 3/7 + 5 3/7 - 4) = (4/7 + 38/7 - 4) = (42/7 - 4)

Step 2: Convert the whole numbers into fractions: (42/7 - 28/7) = (14/7)

Step 3: Simplify the fraction: 14/7 = 2

Now, we have the simplified expression inside the parentheses: (-1 1/7) = -8/7.

Step 4: Multiply the result inside the parentheses with the value outside the parentheses: (-1 1/7) * (-1) = (8/7) * (-1) = -8/7

Therefore, the final result of the expression is -8/7.
