A bookstore had 240 copies of a magazine. Yesterday the bookstore sold $\frac{5}{6}$ of these copies. How many copies were sold yesterday? Write your answer in simplest form.

Step 1 ：Given that the total number of copies is 240 and the fraction sold is \(\frac{5}{6}\).

Step 2 ：To find out how many copies were sold yesterday, we need to multiply the total number of copies by the fraction that represents the amount sold.

Step 3 ：So, we calculate 240 * \(\frac{5}{6}\) = 200.

Step 4 ：To check our work, we can divide 200 by the total number of copies, 240. This gives us \(\frac{5}{6}\), which is the fraction of the total that was sold.

Step 5 ：So, the bookstore sold \(\boxed{200}\) copies of the magazine yesterday.
