Answer:
36 and 63
Explanation:
An integer is any number which is neither a fraction nor a decimal.
All integers are rational numbers but all rational numbers are not integers.
For the given list of numbers:
36 being a rational number is also as integer because it has no fraction part and is a whole number and all whole numbers are integers too.
0.36 is only a rational number and not an integer as it is a decimal number.
6.3 is only a rational number and not an integer as it is a decimal number.
63 being a rational number is also as integer because it has no fraction part and is a whole number and all whole numbers are integers too.
Hence, out of the given numbers 36 and 63 are both rational as well as integers.
