By dividing something. What you divide will depend on what unit rate you want to find. As an example, let's assume that a dozen (12 units) of a certain product cost $48. If you divide $48 by 12 units, you have a unit rate of 4 dollars/unit. (In principle, you can also divide the other way round; in that case you have 1/4 units/dollar.)
48 each
25%% rate:= 12/48 * 100%= 0.25 * 100%= 25%
2.16 to 12 = 0.18 per unit.
12/3 = 4 per unit.

48 for 8 hours as a unit rate is 6 per hour.

Your question hasn't not sufficient details for an answer.
48 each
25%% rate:= 12/48 * 100%= 0.25 * 100%= 25%
If 12 are 1.29, then the rate for 1 (a unit) is 0.1075(1.29/12)
2.16 to 12 = 0.18 per unit.
24.69/12 = 2.0575 per unit.
12/3 = 4 per unit.
Divide both numbers by 12. So 9.00 : 12 = 9.00/12 : 12/12 = 0.75 : 1 So the unit rate is 0.75
48% % rate = 12/25 * 100% = 48%
