Final answer:
To calculate the monthly viewership loss, divide the total viewers lost (9,000) by the number of months (3), resulting in 3,000 viewers lost per month.
Step-by-step explanation:
If a certain TV show lost a total of nine thousand viewers over the past three months, and it lost the same number of viewers each month, the calculation to find the number of viewers lost each month is a simple division problem.
To find out how many viewers the TV show lost each month, we need to divide the total number of viewers lost by the number of months. So, we would take the total viewers lost, which is 9,000, and divide it by the number of months, which is 3.
9,000 ÷ 3 = 3,000
Therefore, the TV show lost 3,000 viewers each month over the past three months.
