Answer 1

1,4 - 1 1/2 · (1 2/5 + 1/5) = -1

1) 1 2/5 + 1/5 = 1 3/5 = 1,6

2) 1 1/2 · 1,6 = 1,5 · 1,6 = 2,4

3) 1,4 - 2,4 = -1

Ответ: (-1).

Answer 2

Ответ:

-1

Пошаговое объяснение:

1) 1. 2/5 + 1/5 = 1. 3/5

2) 1. 1/2 * 1. 3/5 = 3/2 * 8/5 = 3/1 * 4/5 = 12/5 = 2,4

3) 1,4 - 2,4 = -1

Answer 3

To simplify the expression:

1. First, simplify the innermost expressions within the parentheses: 1 2/5 = 7/5 1/5

2. Add the fractions inside the parentheses: 7/5 + 1/5 = 8/5

3. Now, multiply 1 1/2 by the result from step 2: 1 1/2 = 3/2

   (3/2) * (8/5)

4. Multiply the fractions: (3/2) * (8/5) = (3 * 8) / (2 * 5) = 24/10

5. Simplify the fraction: 24/10 = 12/5

So, 1 1/2 * (1 2/5 + 1/5) simplifies to 12/5.
