Ratio & Proportion Solver

About Ratio & Proportion

A ratio compares two quantities of the same kind; a proportion says two ratios are equal. From Class 6 onward, almost every word problem about mixing, sharing, scaling, or percentage has a ratio inside it. The 12 worked examples cover simplifying ratios, the unitary method for direct proportion (price, distance, work), inverse proportion (the classic men-and-days problems), and percentage problems set up as proportions. Each one shows the 'let the unknown be x' setup line explicitly, because that is the step where most students lose half their marks.

What this calculator does

• Step-by-step working. Every intermediate line is shown, in the layout examiners reward in CBSE / ICSE and university scripts.
• Graphs where they help. Functions and equations are plotted so you can see the result rather than just read it.
• Verification. The answer is substituted back into the original problem so you know the working is consistent.
