Answer: To convert a Senary (base 6) number to decimal, we can use the following formula:
Decimal = (5 * 6^4) + (4 * 6^3) + (7 * 6^2) + (2 * 6^1) + (5 * 6^0)
= (5 * 1296) + (4 * 216) + (7 * 36) + (2 * 6) + (5 * 1)
= 6480 + 864 + 252 + 12 + 5
= 7603
So the Senary (base 6) number 54724 is equivalent to the decimal number 7603.
