Question

45/9 + (-5 7/ 2 1/6)- 1 1/3 + 3 3/4 +(- 13/18) решите! !

Answer 1

$4\frac59+\left(-5\frac7{12}\right)-\left(-2\frac16\right)-1\frac13+3\frac34+\left(-\frac{13}{18}\right)=4\frac59-5\frac7{12}+2\frac16-1\frac13+\\+3\frac34-\frac{13}{18}=\frac{41}9-\frac{67}{12}+\frac{13}6-\frac43+\frac{15}4-\frac{13}{18}=\frac{164-201+78-48+135-26}{36}=\\=\frac{102}{36}=2\frac{30}{36}=2\frac56$
