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.
30 : 12 = 5 : 2 or 2.5 : 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 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
