Solve Proportion Equations Now →What is a Proportion Equation?
At its core, a proportion equation states that two ratios are equal. A ratio, in turn, compares two quantities. The general form of a proportion equation is:
a/b = c/d
Where 'a' is to 'b' as 'c' is to 'd'. Proportions can be 'direct' where both values increase together, or 'inverse' where if one increases the other decreases.
Common Percentage Problems Solved with Proportions
Many common percentage questions can be rephrased and solved using a proportion equation. Here are some examples:
- Finding a percentage of a number: What is 15% of 200? Here, you're looking for a part of the whole.
- Finding what percentage one number is of another: 30 is what percent of 150? This is about comparing a part to a whole to find the rate.
- Calculating percentage increase or decrease: What is the percentage change from 80 to 100? This involves finding the difference as a proportion of the original value. For a deeper dive, explore our article on calculating percentage increase.
