This can be written as 12 over 3, i.e. 12/3 which can be simplified to 4/1.
Ratios can also be written as two numbers separated by a colon.
12/3 can thus be expressed as 12 : 3 which again can be simplified to 4 : 1
10 out of 12 is 83 and 1/3%
3 to 4
Yes.
12/20 = 3/5
9/12 = 3/4
It is 1/3
2/3
7/12
12/4 = 3/1 = 3.
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.
The ratio of 12 to 3 can be expressed as 12:3. To simplify it, divide both numbers by their greatest common divisor, which is 3. This reduces the ratio to 4:1. Therefore, the simplified ratio of 12 to 3 is 4:1.
If our ratio was 3:4. Then we would write it as 3/4. Formula A:B = A/B.
