Question

помогите пожалуйста !!!​

Answer 1

$\frac{2}{3} A = \frac{5}{12} \: => A = \frac{5}{12} \times \frac{3}{2} = \frac{5}{8} \\ \frac{5}{12} - B = \frac{1}{8} \: = > B = \frac{5}{12} - \frac{1}{8} = \\ = \frac{10 - 3}{24} = \frac{7}{24} \\ A + B = \frac{5}{8} + \frac{7}{24} = \frac{15 + 7}{24} = \\ = \frac{22}{24} = \frac{11}{12} \\ D) \frac{11}{12}$
