Use \( <,> \), or \( = \) to compare the \( \begin{array}{cc}\begin{array}{ll}\text { (a) } 0.37 & \square 0.39 \\ \text { (b) } 6.4 & \square 6.40 \\ \text { (c) } 0.04 & \square 0.1\end{array} & \square<\square \\ \square>\square & \square=\square \\ \times & 5\end{array} \)

\( \frac { 1 } { 2 } + \frac { 2 } { 3 } + \frac { 3 } { 4 } + \frac { 4 } { 5 } + \frac { 5 } { 6 } + \ldots + \frac { 20 } { 21 } \)

Estimate by rounding to the nearest hundred. \( 996,721 \times 590 \) \( 598,020,000 \)
