Sagot :

Vamos a resolver las siguientes operaciones combinadas de multiplicación y división paso a paso.

### 9.1. [tex]\([-7 \times (9) \times 2] \div (-6)\)[/tex]

1. Primero realizamos la multiplicación en el numerador:
[tex]\[ -7 \times 9 \times 2 = -126 \][/tex]
2. Luego, dividimos el resultado por [tex]\(-6\)[/tex]:
[tex]\[ \frac{-126}{-6} = 21.0 \][/tex]

### Resultado para 9.1:
[tex]\[ [-7 \times (9) \times 2] \div (-6) = 21.0 \][/tex]

### 9.2. [tex]\([-35 \times (-6)] \div (3)\)[/tex]

1. Primero realizamos la multiplicación en el numerador:
[tex]\[ -35 \times (-6) = 210 \][/tex]
2. Luego, dividimos el resultado por [tex]\(3\)[/tex]:
[tex]\[ \frac{210}{3} = 70.0 \][/tex]

### Resultado para 9.2:
[tex]\[ [-35 \times (-6)] \div (3) = 70.0 \][/tex]

### 9.3. [tex]\([-8 \times (-5)] \div (-20)\)[/tex]

1. Primero realizamos la multiplicación en el numerador:
[tex]\[ -8 \times (-5) = 40 \][/tex]
2. Luego, dividimos el resultado por [tex]\(-20\)[/tex]:
[tex]\[ \frac{40}{-20} = -2.0 \][/tex]

### Resultado para 9.3:
[tex]\[ [-8 \times (-5)] \div (-20) = -2.0 \][/tex]

En resumen, los resultados de las operaciones combinadas son:

1. [tex]\([-7 \times (9) \times 2] \div (-6) = 21.0\)[/tex]
2. [tex]\([-35 \times (-6)] \div (3) = 70.0\)[/tex]
3. [tex]\([-8 \times (-5)] \div (-20) = -2.0\)[/tex]
