Các bn ơi giúp mk với chiều mk đi học rồi!!!!!!!!!!!!
tính
\(\frac{0,5+0,\left(3\right)+0,1\left(6\right)}{2,5+1,\left(6\right)+0,8\left(3\right)}\)
Tính
\(\frac{0,5+0,\left(3\right)-0,1\left(6\right)}{2,5+1,\left(6\right)-0,8\left(3\right)}\)
\(\frac{0,5+0,\left(3\right)-0,1\left(6\right)}{2,5+1,\left(6\right)-0,8\left(3\right)}\)= ?
