Question

Put a decimal point at the correct place in the product - $1.005\times 0.04=4020$

Answer 1

Placing the decimal at the correct place in the product-

Count the number of digits after the decimal point in both the numbers, we have $3$ digits after decimal in $1.005$ and $2$ digits in $0.04$

So, place the decimal after five digits from the right in the product. $\left[\because 3+2=5\right]$

Therefore,

$1.005\times 0.04=0.04020$

Hence, the product of $1.005\times 0.04$is $0.04020$
