Question

Решить пример (1/3-1/4)-24-(2 1/5+3 2/7*7/23)*5/16. С объяснением

Answer 1

$( \frac{1}{3} - \frac{1}{4} )-24-(2 \frac{1}{5} +3 \frac{2}{7} * \frac{7}{23} )* \frac{5}{16} \\ \\ 1) \frac{1}{3} - \frac{1}{4} = \frac{4}{12} - \frac{3}{12} = \frac{1}{12} \\ \\ 2) \frac{23*7}{7*23} =1 \\ \\ 3)2 \frac{1}{5} +1=3 \frac{1}{5} = \frac{16}{5} \\ \\ 4) \frac{16*5}{5*16} =1$

$5) \frac{1}{12} -24-1= \frac{1}{12} -25= \frac{1}{12} -24 \frac{12}{12} =-24 \frac{11}{12}$
