What is 78% of 40?

OpenStudy (anonymous):

31.2

OpenStudy (anonymous):

78% can be rewritten as 78/100 so 78% of 40 = 78/100 of 40 = (78/100)*40 = 78*40/100 = 31.2

From the years 1988 through 1996 Steffi Graf won the annual U.S. Open tennis championships five times and Wimbledon seven times. What percent of both tournaments combined during those 9 years was Steffi Graf the women’s champion?

OpenStudy (anonymous):

each tournament is annual so you get 9 wimbledons happening in 9 years and 9 us opens in 9 years. that leaves you with 18 total tournaments. Steffi Graf won 5 US opens and 7 wimbledons for a total of 12 wins Win percentage = total wins/total chances = (12 wins)/(18 tournaments) = 12/18 = 66.6%
