How many places to the right should the decimal point be moved in the number 512.4156 in order that the 6 becomes the hundredths digit?
We are tasked with moving the decimal point so that '6' occupies the hundredths place. Here’s how we accomplish this:
Hence, we moved the decimal point 2 places to the right. The correct answer is .

Determine the numerical value of the shaded area:
Use the pattern: tenths, hundredths, thousandths, ten thousandths. Each place is 10 times smaller than the one before it, just like whole number places but in reverse!
Moving the decimal point right makes the number larger, while moving it left makes it smaller. The digits stay the same, but their place values change.
Think about where the digit needs to go! If it needs to move to a place closer to the decimal point (like from ten thousandths to hundredths), move the decimal right.
Yes! Count how many places the digit needs to jump left to reach the hundredths place. In 512.4156, the 6 needs to jump 2 places left, so move decimal 2 places right.
That's normal! The question asks for the decimal movement, not whether the final number makes practical sense. Focus on where the specific digit lands.
