Tool ID: ratio. Requested language: so. Description language: en. Complete guide translation: no; untranslated sections use English.

## Overview (en)

The Ratio calculator takes two parts, such as 1.5 and 2.5, and returns the ratio reduced to lowest whole-number terms, like 3:5, along with the first part's share of the total as a percentage. Decimals are scaled to exact integers before simplifying, so nothing is truncated or rounded.

## Supported tasks (en)

Simplifies whole numbers and decimals such as 1.5:2.5 to an exact ratio. Both parts cannot be zero, and decimals are not truncated.

## Steps (en)

1. Adjust the values; an initial result is calculated from the defaults.
2. Change the basic settings or open Advanced mode to fine-tune the result.
3. Review and copy or download your result. Pause Live results to run manually. Sources or individual settings above 20,000 characters require an explicit run.

## Settings

- First part (en; key: a; type: number)
- Second part (en; key: b; type: number)

## Limitations (en)

Use finite numbers, valid dates and the ranges shown by each control. Invalid values produce an error without a downloadable result.

## Questions (en)

### How do I simplify a ratio with decimals?

Enter each part as a decimal. The calculator multiplies both parts by a power of ten to make them whole numbers, then divides by their greatest common divisor. 1.5:2.5 becomes 3:5. Each part can have up to 12 digits before the decimal point and 8 after.

### What percentage of the total is each part of a ratio?

The calculator reports the first part of the total as a percentage, computed from the simplified ratio as first / (first + second) × 100. For 3:5, the first part is 37.5% of the total, so the second part is 62.5%.

### Can a ratio include zero or negative numbers?

One part can be zero, but both parts cannot be zero at the same time. Negative values are accepted; when both parts are negative, the signs cancel. If the parts cancel to a zero total, the percentage share is omitted.

### Where is my input processed?

### What are the input limits?

Use finite numbers, valid dates and the ranges shown by each control. Invalid values produce an error without a downloadable result.
