2:1 or 2/1 or 4:2 or 6:3
example:- 1:2 This'll be read as "one is to two"
The phrase "1 in a half" typically refers to the ratio of 1 to 1.5. To express this as a ratio, it can be simplified to 2:3, meaning for every 2 parts of one quantity, there are 3 parts of another.
for example A=2 B=8 the ratio will be 2:8 which is the same as 2/8=0.250 as a decimal then you can either do it mentally or by calculator 0.250*100 is 25 which gives you 25%
Simplification of RatiosExample 1Express the ratio 6 : 9 in its simplest form.Solution:Note: The ratio 2 : 3 is in its simplest form since the numbers 2 and 3 have no common factor.
To express 35 in the ratio of 3 to 2, you first need to find the total parts of the ratio, which is 3 + 2 = 5 parts. Then, divide 35 by 5, yielding 7. Therefore, the two parts of the ratio are 3 parts (3 × 7 = 21) and 2 parts (2 × 7 = 14), meaning 35 can be represented as 21 to 14 in the ratio of 3 to 2.
2% = 1/50

Express the ratio below in its simplest form. 12 : 6
3:2
You express ratio as a fraction. For instance, the ratio of 3 to 4 is 3/4, or .75

1 : 5 ratio
To express a ratio as a unit rate, divide both terms of the ratio by the second term. This simplifies the ratio to a value per one unit of the second term. For example, if you have a ratio of 10 miles to 2 hours, you would divide both numbers by 2, resulting in a unit rate of 5 miles per hour. This indicates how many units of the first quantity correspond to one unit of the second quantity.
48:2. If you want it simplified then it is 24:1.
