Question

1. shade the square to match the expression, then solve it.$0.7 \times 0.4 =$2) calculate the product $93 \times 26$.3) use the results of this and estimation to find the exact product of each of the following:| | estimate | exact product || ---- | ---- | ---- || $0.93 \times 2.6$ | | || $93 \times 0.26$ | | || $9.3 \times 26$ | | || $0.93 \times 0.26$ | | |4) cheese costs $1.80 per pound. samira bought some cheese. she paid with a 5 dollar bill and got $1.40 in change. how many pounds of cheese did she buy?

Explanation:

Step1: Resolver 0.7 × 0.4

$0.7 \times 0.4 = 0.28$
(Nota: Para el recuadro, se somete el 28% del cuadrado: 7 columnas de 10 y 4 filas de 10, la intersección es 28 casillas)

Step2: Calcular 93 × 26

$93 \times 26 = (90 \times 26) + (3 \times 26) = 2340 + 78 = 2418$

Step3: Estimar y calcular productos

Para $0.93 \times 2.6$:

Estimar: $1 \times 3 = 3$
Exacto: $0.93 \times 2.6 = 2.418$

Para $93 \times 0.26$:

Estimar: $90 \times 0.3 = 27$
Exacto: $93 \times 0.26 = 24.18$

Para $9.3 \times 26$:

Estimar: $9 \times 26 = 234$
Exacto: $9.3 \times 26 = 241.8$

Para $0.93 \times 0.26$:

Estimar: $1 \times 0.3 = 0.3$
Exacto: $0.93 \times 0.26 = 0.2418$

Step4: Calcular libras de queso

1. Calcular gasto total: $5 - 1.40 = 3.60$
2. Dividir por precio por libra: $\frac{3.60}{1.80} = 2$

Answer:

1. (Cuadrado con 28 casillas sombreadas) $0.7 \times 0.4 = 0.28$
2. $93 \times 26 = 2418$
3. Tabla de resultados:

Expresión	Estimate	Exact Product
$93 \times 0.26$	$27$	$24.18$
$9.3 \times 26$	$234$	$241.8$
$0.93 \times 0.26$	$0.3$	$0.2418$

1. Samira compró 2 libras de queso.
