e the place value of the underlined digit. \( \begin{array}{ll}\text { 1. } 83.6 \underline{7} \\ \text { 2. } 75 . \underline{9} 9 & 4.1 .86 \\ \text { 3. } 0.80 & 5.65 .4 \underline{3}\end{array} \)

1. For \(83.6\underline{7}\):  The underlined digit is \(7\). In this decimal number the first digit after the decimal point (the \(6\)) is in the tenths place and the second digit – the underlined \(7\) – is in the hundredths place.  Thus, the place value of \(7\) is the hundredths place. 2. For \(75.\underline{9}9\):  Here the underlined digit is the first digit after the decimal point. The first digit to the right of the decimal (the underlined \(9\)) is in the tenths place.  Thus, the place value of \(9\) is the tenths place. 3. For \(65.4\underline{3}\):  In this number the digit immediately after the decimal point, \(4\), is in the tenths place, and the underlined digit \(3\) is in the hundredths place.  Thus, the place value of \(3\) is the hundredths place.
