nhanh lên giùm nha mina

Answer 1

\(4\frac{3}{4}+\left(-0,375\right)+\frac{1}{8}+\left(-1,20\right)+\left(-2,5\right)+\frac{31}{12}\)

\(=\frac{19}{4}+\frac{-3}{8}+\frac{1}{8}+\frac{-6}{5}+\frac{-5}{2}+\frac{31}{12}\)

\(=\frac{570}{120}+\frac{-45}{120}+\frac{15}{120}+\frac{-144}{120}+\frac{-300}{120}+\frac{310}{120}\)

\(=\frac{406}{120}=\frac{203}{60}\)

Answer 2

e nhầm phải là 3\(\frac{1}{12}\)nha
