Question

Evaluate : $2.34\times 8$

Answer 1

Step 1 : Multiply the given decimals ignoring the decimal points

$\Rightarrow 234\times 8=1872$

Step 2 : Add the number of decimal places in each number .

In the product obtained , place the decimal point after the same number of digits ( from right to left ) as the total number of decimal places.

Since , the total number of decimal places in the given decimals is $2$ .So ,we will place the decimal point after two digits from the right to left as $18.72$ .

Hence, $2.34\times 8$ = $18.72$ .
