Question

Find the following product

$3.685\times 100$

Answer 1

Find the product

The place value after the decimal represents the fractional part of the number.
So, we can write $3.685=\frac{3685}{1000}$

Now,

$$\begin{gathered} 3.685\times 100 \\ =\frac{3685}{1000}\times 100 \\ =\frac{3685}{10} \\ =368.5 \end{gathered}$$

Hence, the correct answer is $368.5$.
