[tex]a.\frac{30}{48}=\frac{6*5}{6*8} = \frac{5}{8}\\\\b. \frac{63}{35} = \frac{7*9}{7*5} = \frac{9}{5}\\\\c. \frac{15}{60}=\frac{15*1}{15*4} = \frac{1}{4}\\\\d.\frac{99}{44} = \frac{11*9}{11*4} = \frac{9}{4}\\\\e. \frac{17}{34}=\frac{17*1}{17*2} = \frac{1}{2}\\\\f. \frac{76}{95} = \frac{19*4}{19*5} = \frac{4}{5}\\[/tex]
