Calculate: \(\frac{1}{2.3}+\frac{1}{3.4}+\frac{1}{4.5}+...+\frac{1}{38.39}+\frac{1}{39.40}\) = … (Write your answer by decimal in the simplest form).
Okay ?
\(\frac{1}{2\cdot3}+\frac{1}{3\cdot4}+\frac{1}{4\cdot5}+...+\frac{1}{38\cdot39}+\frac{1}{39.40}\)
\(=\frac{1}{2}-\frac{1}{3}+\frac{1}{3}-\frac{1}{4}+...+\frac{1}{38}-\frac{1}{39}+\frac{1}{39}-\frac{1}{40}\)
\(\frac{1}{2}-\frac{1}{40}\)
= 0,475
