Use the Egyptian Algorithm to Multiply $$12 \times 40$$ A) $\begin{array}{ll}1 & 40 \\2 & 80 \\4 & 160 \\8 & 320\end{array}$

Use the Egyptian algorithm to multiply.
$$12 \times 40$$

A)
$\begin{array}{ll}1 & 40 \\2 & 80 \\4 & 160 \\8 & 320\end{array}$

$160+320=480$

B)
$\begin{array}{ll}1 & 40 \\2 & 80 \\3 & 160 \\4 & 320 \\5 & 640\end{array}$

$160+320+640=1120$

C)
$\begin{array}{ll}1 & 40 \\2 & 80 \\3 & 120 \\4 & 160 \\5 & 200\end{array}$

$120+160+200=480$

D)
$\begin{array}{ll}1 & 40 \\2 & 80 \\4 & 120 \\8 & 160\end{array}$

$120+160=280$
