Answer
a. $\frac{21}{100}$
b. $\frac{1}{2}$
c. Multiplexes
d. $\frac{1}{2}$
Work Step by Step
a. It can be read that $\frac{21}{100}$ of U.S. movie screens are in miniplexes
b. $\frac{1}{25}+\frac{23}{50}=\frac{1*2}{25*2}+\frac{23}{50}=\frac{2}{50}+\frac{23}{50}=\frac{2+23}{50}=\frac{25}{50}=\frac{5*5}{2*5*5}=\frac{1}{2}*\frac{5*5}{5*5}=\frac{1}{2}*1=\frac{1}{2}$
c. It can be read from the pie chart that Multiplexes has the greatest fraction of screens.
d. $\frac{21}{100}+\frac{29}{100}=\frac{21+29}{100}=\frac{50}{100}=\frac{2*5*5}{2*2*5*5}=\frac{1}{2}*\frac{2*5*5}{2*5*5}=\frac{1}{2}*1=\frac{1}{2}$
