D=\(\frac{2}{1.4}+\frac{2}{4\cdot7}+...+\frac{2}{97\cdot100}\)
\(\frac{3}{2}D=\frac{3}{1.4}+\frac{3}{4.7}+...+\frac{3}{97\cdot100}\)
\(\frac{3}{2}D=1-\frac{1}{4}+\frac{1}{4}-\frac{1}{7}+...+\frac{1}{97}-\frac{1}{100}\)
\(\frac{3}{2}D=1-\frac{1}{100}=\frac{99}{100}\)
D=\(\frac{99}{100}:\frac{3}{2}=\frac{33}{50}\)
