Question 9: Choice (A) is the answer
[tex]\frac{1}{5} * x+\frac{1}{3} =\frac{7}{15} \\\\\frac{x}{5}=\frac{7}{15} -\frac{1}{3} = \frac{7}{15} -\frac{1*5}{3*5} =\frac{7-5}{15} \\\\\frac{x}{5} =\frac{2}{15} \\\\15x = 10\\\\x = \frac{10}{15} =\frac{2}{3} ; (A)[/tex]
Question 10: Choice (B) is the answer:
[tex]\frac{4}{6}+x=\frac{11}{12} \\\\x= \frac{11}{12} -\frac{4}{6} =\frac{11}{12} -\frac{4*2}{6*2} =\frac{11-8}{12} \\\\x = \frac{3}{12} =\frac{1}{4}; (B)[/tex]
Hope that helped!
