Fraction to Percent Converter

This tool converts a mixed fraction (integer + numerator/denominator) into its percentage equivalent. It is useful for math homework, financial calculations, or any situation where you need to express fractions as percentages.

The conversion runs entirely in your browser. Enter the integer part (optional), the numerator, and the denominator, then click Calculate to see the percentage result.

How to use

  1. Enter the integer part (leave empty or 0 if the fraction is less than 1).
  2. Enter the numerator (top number of the fraction).
  3. Enter the denominator (bottom number of the fraction).
  4. Click Calculate to see the percentage result.
  5. Use Copy to copy the result to your clipboard, or Clear to reset.

How it works

The percentage is calculated as: percent = (integer + numerator / denominator) * 100. For example, 3/4 becomes (3 / 4) * 100 = 75%.

Example

Fraction:  3/4
Percent:   75%

Fraction:  1/2
Percent:   50%

Fraction:  1 1/4
Percent:   125%

MCP integration

MCP (Model Context Protocol) lets AI agents and apps discover and run Coding.Tools utilities for repeatable conversions, formatting, hashing, and generation workflows.

MCP tool name: fraction-to-percent

MCP endpoint: https://coding.tools/mcp

Call tools/list first. Each tool entry includes inputSchema, outputSchema, and examples so an AI agent or client can build valid arguments without guessing.

For tools/call, read result.content[0].text for the display value and result.structuredContent for machine parsing. Tool-level failures return isError: true; protocol failures return a JSON-RPC error.

Example tools/call request:

curl -s https://coding.tools/mcp \
  -H "Content-Type: application/json" \
  -H "Accept: application/json" \
  -H "MCP-Protocol-Version: 2025-06-18" \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"fraction-to-percent","arguments":{"input":"1/8"}}}'

Most text and data tools accept an input string plus optional options. Browser-only image tools are listed for discovery and return a web UI link when they need browser image APIs.
