Step-by-step explanation:
If we use the rules we say that <span>when we multiply two numbers we get the result in the numbers the least significant number has in the multiplication. So we may proceed like this:</span>
67.6 x 1.2 = 81.12
<span>As the decimal part does not continue indefinitely we can leave the answer as it is.</span><span> if the answer was 81.123612356213 then we leave it like </span><span>81.1 as the rules say</span>
