See a solution process below:

We can rewrite this problem as:

What is 60% of 35?

"Percent" or "%" means "out of 100" or "per 100", Therefore 60% can be written as #60/100#.

When dealing with percents the word "of" means "times" or "to multiply".

Finally, lets call the number of members we are looking for "m".

Putting this altogether we can write this equation and solve for #m# while keeping the equation balanced:

#m = 60/100 xx 35#

#m = 2100/100#

#m = 21#

#color(red)(21)# members must be present to have a vote.
