Question

2 целых 1/3-4÷(3 целых 2/5+9,8)
Помогите пожалуйста!

Answer 1

$3 \frac{2}{5} +9 \frac{4}{5} =12 \frac{6}{5} =13 \frac{1}{5}$
$4:13 \frac{1}{5} =4: \frac{66}{5} = \frac{4*5}{66} = \frac{10}{33}$
$2 \frac{1}{3} - \frac{10}{33} =2 \frac{11-10}{33} =2 \frac{1}{33}$

Answer 2

$2 \frac{1}{3} -4:(3 \frac{2}{5} +9.8) \\ \\ 1)3 \frac{2}{5} +9.8=3.4+9.8=13.2 \\ \\ 2)4:13.2=4: \frac{132}{10} = \frac{4*10}{132} = \frac{10}{33} \\ \\ 3)2 \frac{11}{33} - \frac{10}{33} =2 \frac{1}{33}$
