(3,5/18*3,1/4+2,1/6)*6-7,2/3*3,1/4 Помогите решить пример! Спасибо

Answer 1

$3.5 \div 18 = 0.4 \\ 0.4 \times 3.1 = 1.24 \\ 1.24 \div 4 = 0.31 \\ 2.1 \div 6 = 0.35 \\ 0.35 + 0.31 = 0.66 \\ 0.66 \times 6 = 3.96 \\ 7.2 \div 3 = 2.4 \\ 2.4 \times 3.1 = 7.44 \\ 7.44 \div 4 = 1.86 \\ 3.96 - 1.86 = 2.1$
