Assuming that the "sixty" in the question refers to a whole number, and the "four-hundreths" as part of a whole, then the answer would be 60.04.
In the decimal system, the first digit to the right of the decimal point refers to tenths of a whole. The second digit refers to hundreths of a whole, the third to thousandths of a whole, and so on.

65,000,065
Sixty-five million sixty-five.
Sixty-six and sixty-seven hundredths.
Sixty and sixty-one thousandths (60.061) in standard form is 6.0061 × 101
The quotient is 265.
To write sixty thousandths, you would write it as 0.060. The zero before the decimal point indicates there are no whole numbers, and the six in the hundredths place represents 60 hundredths. The final zero is added as a placeholder to indicate the thousandths place.
60,060 | sixty thousand, sixty.
Sixty hundreds = 6,000
