In decimal notation, what place value does the number 7 in 3.47 represent?

In decimal notation, the position of each digit determines its place value. The number 3.47 can be broken down as follows: the digit 3 is in the whole number place, the digit 4 is in the tenths place, and the digit 7 is in the hundredths place.

Specifically, the number 7 is located two places to the right of the decimal point. This indicates that it represents how many hundredths are present in the value of the whole number. Each place value in a decimal increases or decreases by a factor of ten as you move left or right of the decimal point. Thus, since 7 is in the hundredths place, it confirms that this digit represents a value of 7/100 or 0.07 in decimal form.

The correct answer illustrates the importance of understanding place values in decimal notation, as they define the contribution of each digit to the overall number.
