Question

с объяснениями ,пожалуйста ​

Answer 1

(-1 1/4)*(-25)*(4/5)-(-36):(3/4)+ (-16,5)*(4 1/4)= (5/4*25*4/5)+(36*4/3)-(33/2*17/4)= 25+48-561/8= 23/8= 2,875

Answer 2

$\displaystyle \tt \bigg(-1\frac{1}{4}\bigg)\cdot(-25)\cdot\bigg(+\frac{4}{5}\bigg)-(-36):\frac{3}{4}+(-16,5)\cdot\bigg(+4\frac{1}{4}\bigg)=\\\\\\=1,25\cdot25\cdot0,8+36:0,75-16,5\cdot4,25=\\\\=25+48-70,125=2,825=2\frac{7}{8};$
