Final answer:
To convert 25A base 12 to base 5, you first convert it to base 10 and then convert it to the desired base.
Step-by-step explanation:
To convert a number from one base to another, you need to convert it to base 10 first and then convert it to the desired base. In this case, we want to convert 25A base 12 to base 5. To convert it to base 10, we multiply the digits by the corresponding powers of 12 and sum them up: 2*12^2 + 5*12^1 + 10*12^0. This gives us a value of 354 in base 10. To convert it to base 5, we divide 354 by 5 repeatedly until the quotient is 0, and we record the remainders. The remainders in reverse order give us the digits in base 5, so the answer is 1444 base 5.
