Pregunta 3

Step1: Estimar $0.93×2.6$

Aproximar $0.93≈1$ y $2.6≈3$, así que $1×3=3$. Para el valor exacto:
$$0.93×2.6 = 2.418$$

Step2: Estimar $93×0.26$

Aproximar $93≈90$ y $0.26≈0.3$, así que $90×0.3=27$. Para el valor exacto:
$$93×0.26 = 24.18$$

Step3: Estimar $9.3×26$

Aproximar $9.3≈9$ y $26≈25$, así que $9×25=225$. Para el valor exacto:
$$9.3×26 = 241.8$$

Step4: Estimar $0.93×0.26$

Aproximar $0.93≈1$ y $0.26≈0.3$, así que $1×0.3=0.3$. Para el valor exacto:
$$0.93×0.26 = 0.2418$$

Step1: Calcular costo del queso

Restar el cambio del billete: $5 - 1.40 = 3.60$

Step2: Calcular libras de queso

Dividir costo total por precio por libra: $\frac{3.60}{1.80} = 2$

Answer:

Operación	Estimate	Exact Product
$93×0.26$	27	24.18
$9.3×26$	225	241.8
$0.93×0.26$	0.3	0.2418
