Answer 1

$\displaystyle 1)6,25*8-3\frac{2}{3}:5,5+2,4*4\frac{7}{12}=50-\frac{11}{3}:\frac{11}{2}+\frac{12}{5}*\frac{55}{12}=50-\frac{11}{3}*\frac{2}{11}+11=\\ \\ 50-\frac{1}{3}*2+11=50-\frac{2}{3}+11=61-\frac{2}{3}=\frac{181}{3}=60\frac{1}{3} \\\\ 2)((1\frac{2}{5})^2-1,6):0,12=((\frac{7}{5})^2-\frac{8}{5}):\frac{3}{25}=(\frac{49}{25}-\frac{8}{5})*\frac{25}{3}=\frac{9}{25}*\frac{25}{3}=3$
