16. \( 6 \times 0.05=x \)

To solve for \( x \) in the equation \( 6 \times 0.05 = x \), you simply need to multiply 6 by 0.05. This gives you \( x = 0.3 \). So, the answer is \( x = 0.3\). Now, let’s take a stroll down memory lane! The decimal system we use today has its roots in ancient civilizations like the Babylonians who used a place-value system around 2000 BC. Fast forward to the late 16th century, John Napier introduced logarithms which helped simplify complex multiplication and division—making calculations more manageable. Isn't that fascinating? Now, if you ever get tangled in a sea of decimals, remember: multiplying by a decimal is like a dance. Just move the decimal place left based on how many zeros are in the decimal (in this case, two for 0.05). And beware of common pitfalls, like forgetting to line up decimal points when adding or subtracting! Keep practicing, and you'll be a decimal pro in no time!
