Question

Помогите решить таблицу ​

Answer 1

$-25,7+\left(-13\frac34\right)=-25,7-13,75=-39,45\\\\-17\frac12+(-6,5)=-17,5-6,5=-24\\\\-8,8+\left(-13\frac57\right)=-8\frac8{10}-13\frac57=-8\frac45-13\frac57=-8\frac{28}{35}-13\frac{25}{35}=-22\frac{18}{35}\\\\-2\frac4{15}+\left(-4\frac7{12}\right)=-2\frac4{15}-4\frac7{12}=-2\frac{16}{60}-4\frac{35}{60}=-6\frac{41}{60}\\\\-6,25+\left(-15\frac14\right)=-6,25-15,25=-21,5\\\\-0,09+(-8,2)=-0,09-8,2=-8,29$
