. A group of people is standing in a line at a movie theatre. Three-eights of the people were boys and one-quarter of the people were girls. How much of the group were adulis?

Add Fractions for Boys and Girls: First, add the fractions for the boys and girls to see how much of the group they make up together. $\newline$ $\frac{3}{8}$ (boys) + $\frac{1}{4}$ (girls) = $\frac{3}{8} + \frac{2}{8}$ (since $\frac{1}{4}$ is the same as $\frac{2}{8}$ )
Do the Addition: Now, do the addition. $\frac{3}{8} + \frac{2}{8} = \frac{5}{8}$ So, $\frac{5}{8}$ of the group are either boys or girls.
Find Fraction of Adults: To find out how much of the group were adults, subtract the fraction of boys and girls from the whole group. $1$ (whole group) - $\frac{5}{8}$ (boys and girls) = $\frac{3}{8}$
Find Fraction of Adults: To find out how much of the group were adults, subtract the fraction of boys and girls from the whole group. $\newline$ $1$ (whole group) - $\frac{5}{8}$ (boys and girls) = $\frac{3}{8}$ So, $\frac{3}{8}$ of the group were adults.
