Any number that you can completely write down with digits is rational.
There are an infinite number of them between 4.2 and 6.3 .
Here are a few:
4.2000000001
5
5.9
5.99

6
6.1
6.2
6.2001
6.2002
6.2003
.
.
etc.
Take the average of the two. The average of two rational numbers is (a) rational, and (b) between the two numbers.
42
63
42 / 63 = 66.666666666667%
43, 45, 47, 49, 51, 53, 55, 57, 59, 61, and 63
.95 is a rational number or square root of 121 a rational number
The integer / whole number between 63 and 65 is 64. Any number that you can write down that's more than 63 and less than 65 is a rational number between 63 and 65. There are an infinite number of them, including . . . 63.0000000001 63.01 63.1 63.99909990901 64 64.00001 . . etc.
Take the average of the two. The average of two rational numbers is (a) rational, and (b) between the two numbers.

6.3 IS a rational number. In the form of a ratio, it is 63/10.
63
33% To find out this out, subtract the larger number by the smaller number (63 - 42). Then divide the result (21) by the original number (63) and then you get the answer (21 divided by 63 = 0.333... = 33.333...%
Any number that can be expressed as a fraction is rational. 0.63 = 63/100
42 percent of 150 is 0.42*150 or 63. And conversely, 150% of 42 is 63 as well.
It is a rational number because it can be expressed as a fraction in the form of 63/50
