Помогите решить 1/3+1/2·(2,3-0,061÷0,2)

Решите задачу:

$\frac{1}{3} + \frac{1}{2}*(2,3- \frac{0,061}{0,2} ) \\ \\ \frac{61}{1000} : \frac{2}{10} =\frac{61}{1000} *\frac{10}{2} = \frac{61}{200} =0,305 \\ \\ 2,3-0,305=1,995 \\ \\ \frac{1}{2} *1,995=\frac{1}{2} * \frac{1995}{1000} = \frac{1995}{2000} \\ \\ \frac{1}{3} +\frac{1995}{2000}= \frac{2000+3*1995}{6000} = \frac{7985}{6000}= \frac{1597}{1200}$
