Step 1
a) $7.456×8$
Factor:
$\frac{233×{2}^{5}}{{5}^{3}}$
$=59\frac{81}{125}$
$=59.648$ Step 2
b) $56×35$
First line up the numbers vertically and match the places from the right like this.
$\begin{array}{c}56\\ ×35\phantom{\rule{1em}{0ex}}\\ \end{array}$
Now multiply the first number with the ${1}^{st}$ digit in ${2}^{nd}$ 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.
$\begin{array}{c}56\\ ×35\phantom{\rule{1em}{0ex}}\\ 280\end{array}$
Now multiply the first number with the ${2}^{nd}$ digit in $2{n}^{nd}$ 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.
$\begin{array}{c}56\\ ×35\phantom{\rule{1em}{0ex}}\\ 280\\ 168\phantom{\rule{1em}{0ex}}\\ \end{array}$
$\begin{array}{c}56\\ ×35\phantom{\rule{1em}{0ex}}\\ 280\\ 168\phantom{\rule{1em}{0ex}}\\ 1960\end{array}$
