To find n-number of rational numbers between the rational numbers a and b,
Multiply each rational number by n+1n+1.
Since, there exist n number of integers between a and b.
(i)
To find 5 rational numbers between −1 and 0 , multiply the numbers by 66
−1×66=−66
0×66=06
Integers between −6 and 0 are −5,−4,−3,−2,−1
Now, 5 rational numbers between −66 and 06
are −56,−46,−36,−26,−16
i.e., −56,−23,−12,−13,−16
(ii)
To find 5 rational numbers between −2 and −1 , multiply the numbers by 66
−2×66=−126
−1×66=−66
Integers between −12 and −6 are −11,−10,−9,−8,−7
Now, 5 rational numbers between −126 and −66
are −116,−106,−96,−86,−76
i.e., −116,−53,−32,−43,−76
Note: There exist infinite number of rational numbers between any two distinct rational numbers.
