Difference?
A ratio can be written in three different ways and all are read as "the ratio of x to y"
A proportion on the other hand is an equation that says that two ratios are equivalent.
How to Solve?
For any two quantities say a and b, in order to find the ratio, the formula for ratio is defined as a : b ⇒ a/b, where,
a = the first term or antecedent.
b = the second term or consequent.
For example, ratio 2 : 7 is represented by 2/7, where 2 is antecedent and 7 is consequent. 2 : 7 is the required ratio.
Now, in order to find proportion for the two ratios, a:b and c:d. Then,
a : b :: c : d ⟶ a /b = c /d
The two terms b and c are called mean terms.
The two terms a and d are known as extreme terms.
