Question

Multiply $3.5\times 0.56$

Answer 1

Multiplying decimal numbers-

Ignore the decimal point and multiply

$35\times 56=1960\left[\because 056=56\right]$

Count the number of digits after the decimal point in both the numbers, we have $1$digit after decimal in $3.5$ and $2$digits in $0.56$

So, place the decimal after three digits from the right in the product. $\left[\because 1+2=3\right]$

$3.5\times 0.56=1.960$

Hence , product of $3.5\times 0.56$ is $1.960$
