Question

80 members decreased by 65%

Answer 1

80 members* (65/100)= 52 members

80 members- 52 members= 28 members

The final answer is 28 members~

Answer 2

there are now 28 members
all you do is 80 times 0.65 = 52
but you still have to subtract 80 - 52 to find the number of members left
SOOOO
28 members still there
52 members quit
