Given:
45,000 seats
5/8 of the seats were bought for the next game.
To get the exact number of seats, we need to multiply the total number of seats by the fraction bought.
45,000 * 5/8 = (45,000 * 5) / 8 = 225,000 / 8 = 28,125 seats
5/8 of the total seats is 28,125 seats which are all unavailable.
8/8 - 5/8 = 8-5/8 = 3/8 is the fraction of the seats available.
45,000 - 28,125 = 16,875 seats available.
45,000 * 3/8 = (45,000 * 3) / 8 = 135,000 / 8 = 16,875
