Question

Multiply $1.2$ by $0.8$

• A. $0.96$
• B. $9.6$
• C. $96$
• D. None of the above

Answer 1

The correct option is A $0.96$

Multiplication of $1.2$ and $0.8$
$=1.2\times 0.8$
$=\frac{12}{10}\times \frac{8}{10}$
$=\frac{12\times 8}{100}$
$=\frac{96}{100}$
$=0.96$
We can get $0.96$ as by first multiplying $12$ by $8$
We get $12\times 8=96$
Now, we put decimal point after $9$ to get $0.96$
So, $1.2\times 0.8=0.96$
