Question

which three models have equal values?
$5 \times 96$
$5 \times 69$
$5 \times (60 + 9)$
$5 \times (6 + 9)$
$(5 \times 9) + (5 \times 6)$
$(5 \times 60) + (5 \times 9)$

Explanation:

Step1: Calcular $5 \times 69$

$5 \times 69 = 345$

Step2: Calcular $5 \times (60+9)$

$5 \times (60+9) = 5 \times 69 = 345$

Step3: Calcular $(5 \times 60)+(5 \times 9)$

$(5 \times 60)+(5 \times 9) = 300 + 45 = 345$

Step4: Verificar otros valores

$5 \times 96 = 480$; $5 \times (6+9)=5 \times 15=75$; $(5 \times 9)+(5 \times 6)=45+30=75$

Answer:

Las expresiones con valores iguales son:
$5 \times 69$, $5 \times (60+9)$ y $(5 \times 60) + (5 \times 9)$
