Arrange the following numbers in order, from smallest to largest \[ \begin{array}{ccccc} 0.7 & \frac{2}{3} & 0.65 & \frac{3}{5} & \frac{5}{8} \\ A & B & C & D & E \end{array} \]

Step 1 ：Convert all the numbers to decimals: \(0.7, \frac{2}{3} \approx 0.67, 0.65, \frac{3}{5} = 0.6, \frac{5}{8} = 0.625\)

Step 2 ：Arrange the numbers in ascending order: \(\boxed{\frac{3}{5} (0.6), \frac{5}{8} (0.625), 0.65, \frac{2}{3} (0.67), 0.7}\)
