There was a decrease of 20% in membership from October to November.

Step-by-step explanation:

Step 1; To find the percent by which the running clubs membership decreased we must find the difference between the number of members in October and the number of members in November. The number of members in the club in October was 25 whereas it reduced to 20 in the month of November.

Difference in members = Number of members in October - Number of members in November = 25 - 20 = 5

Step 2; To find the percent decrease in number of members in the running club, we divide the difference in number of members by the number of members in November. We multiply this value by 100 to get it in terms of percentage.

Percent decrease in number of members = (Difference in members / number of members in November) * 100

= (5/25) * 100 = 0.20 * 100 = 20%

So number of members in the club decreased by 20% from October to November.
