\(x\times2+x\times\dfrac{1}{5}=1.\dfrac{1}{3}\\ \Rightarrow x\times\left(2+\dfrac{1}{5}\right)=\dfrac{1}{3}\\ \Rightarrow x\times\dfrac{11}{5}=\dfrac{1}{3}\\ \Rightarrow x=\dfrac{5}{33}\)

Điền chữ số thích hợp vào ô trống:
6,46.... < 6,416
5,518 < 5,51...
Tìm chữ số x biết 49,94 > 49,9x.
1.1; 2; 3
2.0; 1; 2; 3; 4
3.0; 2; 3
4.0; 1; 2; 3
(x+0.3)+(x+0.7)+(x+1.1)+.......+(X+4.7)+(x+5.1)=48.1
( x + 0.3 ) + ( x + 0.7 ) + ( x + 1.1 ) + ... + ( x + 4.7 ) + ( x + 5.1 ) = 48.1
