Explanation:

Explicación:

Paso 1: Resolver las divisiones simples

Usar la relación: $dividendo = cociente \times divisor$ o $divisor = \frac{dividendo}{cociente}$
a. $45 \div \_\_ = 9$ → $divisor = \frac{45}{9}=5$
b. $\_\_ \div 8 = 8$ → $dividendo = 8 \times 8=64$
c. $36 \div \_\_ = 9$ → $divisor = \frac{36}{9}=4$
d. $\_\_ \div 8 = 6$ → $dividendo = 6 \times 8=48$
e. $36 \div \_\_ = 6$ → $divisor = \frac{36}{6}=6$
f. $63 \div 7 = \_\_$ → $cociente = \frac{63}{7}=9$

Paso 2: Resolver divisiones con múltiplos

Aplicar la propiedad de que al multiplicar dividendo y divisor por 10/100, el cociente se ajusta:
a. $450 \div 9 = \_\_$ → $\frac{450}{9}=50$
b. $640 \div \_\_ = 8$ → $divisor = \frac{640}{8}=80$
c. $360 \div 90 = \_\_$ → $\frac{360}{90}=4$
d. $480 \div \_\_ = 80$ → $divisor = \frac{480}{80}=6$
e. $3600 \div \_\_ = 6$ → $divisor = \frac{3600}{6}=600$
f. $6300 \div 7 = \_\_$ → $\frac{6300}{7}=900$

Respuesta:

a. $45 \div \boldsymbol{5} = 9$; $450 \div 9 = \boldsymbol{50}$
b. $\boldsymbol{64} \div 8 = 8$; $640 \div \boldsymbol{80} = 8$
c. $36 \div \boldsymbol{4} = 9$; $360 \div 90 = \boldsymbol{4}$
d. $\boldsymbol{48} \div 8 = 6$; $480 \div \boldsymbol{6} = 80$
e. $36 \div \boldsymbol{6} = 6$; $3600 \div \boldsymbol{600} = 6$
f. $63 \div 7 = \boldsymbol{9}$; $6300 \div 7 = \boldsymbol{900}$
