$\frac{ \frac{1}{2} + \frac{1}{2} \div 2 }{x} = \frac{6}{7}$

Answer 1

[tex] \frac{ \frac{1}{2}+ \frac{1}{2}. \frac{1}{2} }{x} = \frac{6}{7} \\ \frac{ \frac{1}{2}+ \frac{1}{4}}{x} = \frac{6}{7} \\ \frac{ \frac{2+1}{4}}{x}= \frac{6}{7} \\ \frac{3}{4}. \frac{1}{x} = \frac{6}{7} \\ \frac{3}{4x}= \frac{6}{7} \\ 21=24x \\ x= \frac{21}{24} [/tex]

Answer 2

$\frac{1}{2} + \frac{1}{2} \div 2 \: supra \: x = \frac{6}{7} \\ \frac{2}{2} \times \frac{1}{2} supra \: x = \frac{6}{7} \\ \frac{1}{2} supra \: x = \frac{6}{7} \\ \frac{0.5}{x} = \frac{6}{7} \\ = > x = \frac{7 \times 0.5} {6} \\ = > x = \frac{3.5}{6} \\ = > x = 0.58(3)$
