+<pre>
++-----------------------------+---------+
+| Column Name                 | Type    |
++-----------------------------+---------+
+| delivery_id                 | int     |
+| customer_id                 | int     |
+| order_date                  | date    |
+| customer_pref_delivery_date | date    |
++-----------------------------+---------+
+delivery_id is the primary key (column with unique values) of this table.
+The table holds information about food delivery to customers that make orders at some date and specify a preferred delivery date (on the same order date or after it).
+</pre>
+
+<p>&nbsp;</p>
+
+<p>If the customer&#39;s preferred delivery date is the same as the order date, then the order is called <strong>immediate;</strong> otherwise, it is called <strong>scheduled</strong>.</p>
+
+<p>Write a solution to find the percentage of immediate orders in the table, <strong>rounded to 2 decimal places</strong>.</p>
+
+<p>The result format is in the following example.</p>
