so these are decmials of the accutal total so
.32=32%
what makes this question easy is that there are 200 members so to convert the percents into accutall numbers so like .32=32%=64 people (since 200 is 2 times of 100)
A. fiction of 3140 compared to 2130
fiction 3140=.38=38%=76 readers
fiction 2130=.32=32%=64 readers
7664=12
A is FALSE
B. so we want to know how many people are 3140 and prefer fiction
so .38=38% and 38% of 200=76
B is FALSE
C 43 members are 2130
so we look at the total row for the 2130 people and see that .43 or 43% or 86 people are in the 2130 age group
C is FALSE
D. 140 members prefer fiction
look at the total column for fiction and see that .70 like fiction .70=70%=140 people
D is TRUE
so A,B,C are FALSE
D is TRUE
