Members that voted yes : members that voted no = 5 : 1

Total ratio = 5 + 1 = 6

total school board members that voted = 18

how many voted yes for new math books?

Members that voted yes = 5/6 × 18

= 0.8333333333333 × 18

= 15 members

Members that voted yes = 15 Members

members that voted no = 1/6 × 18

= 0.1666666666666 × 18

= 3

members that voted no = 3 members
