About

Calculating a fraction of a number is a frequent requirement in cooking, carpentry, and financial planning. However, dealing with mixed numbers or improper fractions can lead to confusion. This tool breaks down the logic of ab ร— n into clear, manageable steps.

Instead of just providing a raw decimal, our engine visualizes the process: first multiplying the whole number by the numerator, then dividing by the denominator. It handles simplification automatically (GCD algorithm) and generates a proportional pie chart to assist visual learners in grasping the magnitude of the result relative to the whole.

Formulas

The core operation is multiplication of the whole number by the fraction:

Result = Number ร— NumeratorDenominator

This is computationally equivalent to:

Result = (Number ร— Numerator)Denominator

Frequently Asked Questions

First, multiply the number by the top part of the fraction (numerator, 2). Then, press the divide button and enter the bottom part (denominator, 3). For example, for 2/3 of 90: 90 ร— 2 = 180, then 180 รท 3 = 60.
Yes. Convert the mixed number to an improper fraction first. 1 1/2 becomes 3/2. Then proceed with the standard multiplication: Number ร— 3 รท 2.
If the whole number is not perfectly divisible by the denominator, the result will be a decimal. For example, 1/3 of 10 is 3.333... This tool shows both the exact fractional remainder and the decimal approximation.
The formula is (Whole Number ร— Numerator) รท Denominator.
