Question

3 целых 6/7 * 7,6 - 2,06 * 3 целых 6/7 - 7,4 * 3 целых 6/7 = ?

Answer 1

$3 \frac{6}{7} +7.6-2.06*3 \frac{6}{7} -7.4*3 \frac{6}{7} = \frac{27}{7} + \frac{38}{5} - \frac{103}{50} * \frac{27}{7} - \frac{37}{5} * \frac{27}{7}=$ $\frac{27}{7} + \frac{38}{5} - \frac{2781}{350} - \frac{999}{35} =- \frac{8761}{350} =-25 \frac{11}{350}$
