Answer 1

Ответ:

- d.

Пошаговое объяснение:

2 2/5×d×(-5/12) = (-5/12 • 2 2/5)•d = -5/12•12/5•d = -1•d = - d.

Answer 2

To solve the expression $2 \frac{2}{5} \times d \times \left(-\frac{5}{12}\right)$, follow these steps:

Step 1: Convert the mixed number $2 \frac{2}{5}$ to an improper fraction:

$$2 \frac{2}{5} = \frac{(2 \times 5) + 2}{5} = \frac{10 + 2}{5} = \frac{12}{5}$$

So, the expression becomes $\frac{12}{5} \times d \times \left(-\frac{5}{12}\right)$.

Step 2: Multiply the fractions:

$$\frac{12}{5} \times \left(-\frac{5}{12}\right) = \frac{12 \times (-5)}{5 \times 12} = \frac{-60}{60} = -1$$

So, the expression simplifies to:

$$-1 \times d = -d$$

Therefore, the result is $-d$.
