Ratio Calculator
Simplify any two-number ratio to its lowest terms and explore equivalent ratios in seconds. Ideal for cooking, map scaling, financial analysis, and mixing solutions where proportional relationships matter.
Percentage Calculator
Find what a given percentage of a number is β for example, 18% of a $42 restaurant bill, or 7.5% sales tax on a $129 purchase. This calculator handles the most common percentage question that comes up in everyday math: "what is P% of N?" Enter the percentage and the base number, and you get the exact partial amount. It is the building block behind tip calculators, discount calculators, tax calculators, and most quick financial estimates you do on the fly.
