Given the ratio 3:4, we can express this in different ways.

75% - Percent 3/4 - Fraction 3:4 - Ratio

However, I was looking for a word to describe a ratio expressed just as a simple decimal value, or a number represented as per-ten or per-dec.

0.75 - per-unit 7.5 - per-dec

But is there an official term for these?

See Fraction : "A common fraction is a numeral which represents a rational number. That same number can also be represented as a decimal, a percent, or with a negative exponent. For example, $0.01, 1%$, and $10^{−2}$ all equal the fraction $\dfrac {1} {100}$." – Mauro ALLEGRANZA Mar 26 '19 at 12:13
...and of course there is the somewhat archaic per mille. – J. M. ain't a mathematician Mar 26 '19 at 13:00
