Answer: There will be five decimal places in total.

Explanation:

Since we have given that


(0.004)(3.42)

We have to write as a fraction multiplication problem:


(4)/(1000)* (342)/(100)\\\\=(1368)/(100000)\\\\=0.01368

The answer is in the hundredths-thousandths i.e. five decimal places because first expression is in thousandths i.e. there are 3 decimal places and second expression is in hundredths i.e. there are 2 decimal places .

So, there will be five decimal places in total.
