Question

1. use place value and properties to multiply.

$900 \times 3 = \underline{\quad\quad} \times 100 \times 3$
$= 9 \times \underline{\quad\quad} \times 100$
$= \underline{\quad\quad} \times 100$
$= \underline{\quad\quad}$

Explanation:

Step1: Reescribir 900 como factor

$900 = 9 \times 100$

Step2: Sustituir en la multiplicación

$900 \times 3 = 9 \times 100 \times 3$

Step3: Agrupar factores enteros

$= 9 \times 3 \times 100$

Step4: Calcular producto de enteros

$9 \times 3 = 27$

Step5: Multiplicar por 100

$27 \times 100 = 2700$

Answer:

$900 \times 3 = \boldsymbol{9} \times 100 \times 3$
$= 9 \times \boldsymbol{3} \times 100$
$= \boldsymbol{27} \times 100$
$= \boldsymbol{2700}$
