y : 0,5 + y x 0,5 = 0,75
y x 2 + y x 0,5 = 0,75
y x (2+ 0,5) = 0,75
y x 2,5 = 0,75
y = 0,75 :2,5
y =0,3

\(A=\frac{3+1-1}{1x2x3}+\frac{4+2-1}{2x3x4}+\frac{5+3-1}{3x4x5}+...+\frac{1010+1008-1}{1008x1009x1010}.\)
\(A=\frac{1}{1x2}+\frac{1}{2x3}-\frac{1}{1x2x3}+\frac{1}{2x3}+\frac{1}{3x4}-\frac{1}{2x3x4}+\frac{1}{3x4}+\frac{1}{4x5}-\frac{1}{3x4x5}+...+\)
\(+\frac{1}{1008x1009}+\frac{1}{1009x1010}-\frac{1}{1008x1009x1010}\)
\(A=\frac{1}{1x2}+\left(\frac{2}{2x3}+\frac{2}{3x4}+\frac{2}{4x5}+...+\frac{2}{1009x1010}\right)+\)
\(-\left(\frac{1}{1x2x3}+\frac{1}{2x3x4}+\frac{1}{3x4x5}+...+\frac{1}{1008x1009x1010}\right)\)
Đặt
\(B=\frac{2}{2x3}+\frac{2}{3x4}+\frac{2}{4x5}+...+\frac{2}{1009x1010}\)
\(\frac{B}{2}=\frac{1}{2x3}+\frac{1}{3x4}+\frac{1}{4x5}+...+\frac{1}{1009x1010}\)
\(\frac{B}{2}=\frac{3-2}{2x3}+\frac{4-3}{3x4}+\frac{5-4}{4x5}+...+\frac{1010-1009}{1009x1010}\)
\(\frac{B}{2}=\frac{1}{2}-\frac{1}{3}+\frac{1}{3}-\frac{1}{4}+\frac{1}{4}-\frac{1}{5}+...+\frac{1}{1009}-\frac{1}{1010}\)
\(\frac{B}{2}=\frac{1}{2}-\frac{1}{1010}\Rightarrow B=1-\frac{1}{505}\)
Đặt \(C=\frac{1}{1x2x3}+\frac{1}{2x3x4}+\frac{1}{3x4x5}+...+\frac{1}{1008x1009x1010}\)
\(2xC=\frac{3-1}{1x2x3}+\frac{4-2}{2x3x4}+\frac{5-3}{3x4x5}+...+\frac{1010-1008}{1008x1009x1010}\)
\(2xC=\frac{1}{1x2}-\frac{1}{2x3}+\frac{1}{2x3}-\frac{1}{3x4}+\frac{1}{3x4}-\frac{1}{4x5}+...+\frac{1}{1008x1009}-\frac{1}{1009x1010}\)
\(2xC=\frac{1}{1x2}-\frac{1}{1009x1010}\Rightarrow C=\frac{1}{4}-\frac{1}{1009x2020}\)
\(\Rightarrow A=\frac{1}{2}+B-C=\frac{1}{2}+\left(1-\frac{1}{505}\right)-\left(\frac{1}{4}-\frac{1}{1009x2020}\right)\)
