To find five rational numbers between \(\frac{3}{5}\), and\(\frac{4}{5}\).
There are infinite rational numbers between.
\(\frac{3}{5}=\frac{3×6}{5×6}=\frac{18}{30}\)
\(\frac{4}{5}=\frac{4×6}{5×6}=\frac{24}{30}\)
Therefore, rational numbers between \(\frac{3}{5}\) and \(\frac{4}{5}\) are
\(\frac{19}{30},\frac{20}{30},\frac{21}{30},\frac{22}{30},\frac{23}{30},\)
Length (in hours) | Number of lamps |
|---|---|
300 − 400 | 14 |
400 − 500 | 56 |
500 − 600 | 60 |
600 − 700 | 86 |
700 − 800 | 74 |
800 − 900 | 62 |
900 − 1000 | 48 |
