Question

Помогите решить по действиям:
$(3.24 \div \frac{9}{7} - 3 \frac{1}{5} \div 1 \frac{1}{3} ) \div ( - 0.9)$

Answer 1

$1).$
$3,24: \frac{9}{7} =\frac{324}{100}* \frac{7}{9} =\frac{252}{100}$
$2).$
$\frac{16}{5}: \frac{4}{3} = \frac{16}{5}* \frac{3}{4} = \frac{4*3}{5*1} = \frac{12}{5} =2,4$
$3).$
$\frac{252}{100} -\frac{240}{100}=\frac{12}{100}$
$\frac{12}{100}*(-\frac{10}{9})=- \frac{4*1}{10*3} =- \frac{4}{30} =-\frac{2}{15}$
