A. 3.6363636363...

This can be expressed as a simple fraction. The infinite repeating decimal can be written as 3.(63), where the digits in parentheses repeat infinitely. To convert this to a fraction, we let x = 3.(63) and multiply both sides by 100, so 100x = 363.(63). Then, we subtract the equation 100x = 3.(63) from 100x = 363.(63) to eliminate the decimal part. This gives us:
100x - x = 363.(63) - 3.(63)
99x = 360
x = 360/99
Therefore, 3.(63) can be expressed as the fraction 360/99, which simplifies to 40/11.

Thus, A. 3.6363636363... can be expressed as the simple fraction 40/11.

This number cannot be expressed as a simple fraction because it is a non-repeating decimal. It is a finite decimal with many decimal places and does not have a pattern to repeat. As such, it cannot be represented as a fraction with whole numbers in the numerator and denominator.
