Question

multiply.
\

$$\begin{array}{r} 70.6 \\\\ \\times\\ 53.9 \\\\ \\hline \\end{array}$$

Explanation:

Step1: Ignore decimals, multiply integers

$706 \times 539 = 706 \times (500 + 30 + 9)$
$= 706 \times 500 + 706 \times 30 + 706 \times 9$
$= 353000 + 21180 + 6354$
$= 353000 + 21180 = 374180$
$374180 + 6354 = 380534$

Step2: Count total decimal places

70.6 has 1 decimal place, 53.9 has 1 decimal place. Total: $1+1=2$ decimal places.

Step3: Apply decimal to product

Place decimal in 380534 to get 2 decimal places from the right: $3805.34$

Answer:

$3805.34$
