Answer 1

$(11,75 - x ) -1\frac{5}{6} = 4\frac{7}{8} \\\\11,75 - x = 4\frac{7}{8} + 1\frac{5}{6}\\\\11,75 - x = \frac{39}{8} + \frac{11}{6}\\\\11,75 - x = \frac{117}{24} +\frac{44}{24} \\\\11,75 - x = \frac{161}{24}\\\\- x = \frac{161}{24} - 11,75\\\\-x = \frac{161}{24} - \frac{47}{4}\\\\-x = \frac{161}{24} - \frac{282}{24}\\\\-x = -\frac{121}{24}\\\\x = 5\frac{1}{24}$
