Step 1
a) $7.456 \times 8$
Factor:
$\frac{233 \times 2^{5}}{5^{3}}$
$= 59 \frac{81}{125}$
$= 59.648$ Step 2
b) $56 \times 35$
First line up the numbers vertically and match the places from the right like this.
$\begin{matrix} 56 \\ \times 35 \end{matrix}$
Now multiply the first number with the $1^{s t}$ digit in $2^{n d}$ number to get intermediate results. That is Multiply 56 with 5. Write the result 280 at the end leaving 0 spaces to the right like this.
$\begin{matrix} 56 \\ \times 35 \\ 280 \end{matrix}$
Now multiply the first number with the $2^{n d}$ digit in $2 n^{n d}$ number to get intermediate results. That is Multiply 56 with 3. Write the result 168 at the end leaving 1 spaces to the right like this.
$\begin{matrix} 56 \\ \times 35 \\ 280 \\ 168 \end{matrix}$
Now add the intermediate results to get final answer.
$\begin{matrix} 56 \\ \times 35 \\ 280 \\ 168 \\ 1960 \end{matrix}$
