It is: 18 to 12
You must have seen expressions such as 3:4::12:16, which reads 3 is to 4 as 12 is to 16. Sometimes encountered as 5:a::30:b, which is read 5 is to a as 30 is to b. Is this the type of ratio to which you refer.
Use the sine ratio: sine 30 = opposite/12 opposite = 12*sine 30 opposite = 6 inches
2 to 3
There are 12 inches to 1 foot, so the ratio is 12 to 1.
12 : 12 : 6 30 = (12x2) + (6x1) so ratio will be 12 : 12 : 6 = 2 : 2 : 1
30/12= 5/2=========factor out a 6
5:2
It is: 18 to 12
30/12 = 5/2 or 5 : 2
In a class of 30, if there are 12 boys then there must be 18 girls. This would make the ratio: 18:12 or 3:2 (girls:boys)
12.0 : 30.0 = 40.0%
The ratio of 30 to 12 is 30:12, which can be simplified by dividing both numbers by their greatest common factor, which is 6. This simplifies the ratio to 5:2. Ratios are used to compare the quantities of two numbers and show how many times one number contains the other.

The Least Common Multiple (LCM) of (12,30) is 60.The lowest common multiple for two numbers can be calculated by:1. Considering the relationship as a ratio.2. Simplifying the ratio (if possible)3. multiplying each original number by the "opposite" ratio.So 12 and 30 are in the ratio of 12 to 30, that is 12:30. This can be simplified to 2:5. You will notice that if we now multiply the 12 by the 5 and the 30 by the 2 we will reach the same answer of 60. 60 is therefore the LCM.
If you mean 30/12 then it is 5/2 in its simplest form
Use the sine ratio: sine 30 = opposite/12 opposite = 12*sine 30 opposite = 6 inches
