Юленька194 $1 \frac{1}{3} - \frac{3}{4} *( \frac{5}{12} - \frac{1}{3} )= 1 \frac{1}{3} - \frac{3}{4} * \frac{5}{12} +\frac{3}{4} * \frac{1}{3} =1 \frac{1}{3} - \frac{1}{4} * \frac{5}{4} +\frac{1}{4} * \frac{1}{1} =$ $1 \frac{16}{48} - \frac{15}{48} +\frac{12}{48} =1\frac{1}{48} +\frac{12}{48}=1\frac{13}{48}$
