Question

Multiply

$4.007\times 8.06$

Answer 1

Step 1: Convert the decimal into fraction

Remove the decimal point and count the number of digits after the decimal.

Append number of zeroes to $1$ and put the term in the denominator of the number obtained after removing the decimal point from the given number.

So, $4.007=\frac{4007}{1000}$ and $8.06=\frac{806}{100}$

Step 2: Multiplying $\frac{4007}{1000}$ and $\frac{806}{100}$

$\Rightarrow \frac{4007}{1000}\times \frac{806}{100}=\frac{3229642}{100000}$

$=32.29642$

Hence, $4.007\times 8.06$ $=32.29642$
