Guide updated:
Calculate common and decimal fractions, compare values, simplify fractions and show school-style long arithmetic steps.
Practical instructions with desktop and phone screenshots, short demonstrations and answers to common questions.
Before you start
Open the tool in a current browser. The values in the recording are synthetic examples. Check the units, assumptions and limitations before using your own measurements.
Step-by-step instructions
- Open the tool using the button next to the video. Keep the default mode unless the next step specifies a different one.
- Calculate common and decimal fractions, compare values, simplify fractions and show school-style long arithmetic steps.
- Use the demonstration values shown below, or enter your own values with the same units. Keep the example mode while following the recording.
- Inspect the result shown below the inputs. If the tool has an action button, press it after editing; live converters update as you type.
- Copy or export the result using the controls provided by this tool. Check the output before using it in another application.
On a computer
Use the keyboard to enter the example values. Review the options, then inspect the output and use Copy or an export action when available.
On a phone
Tap the input field and enter the example. Close the on-screen keyboard to review the options and result; keep the tab open until you finish.
In Safari on iPhone, open the sharing menu and choose Save to Files if the result opens in a new tab. In Android Chrome, check Downloads. Keep this tab open until processing finishes.
For a better result

Questions and troubleshooting
Does this demonstration use my real data?
No. The recording uses public example values created for the guide. The service operates on the input you enter in your own browser.
What should I check before relying on the result?
This is an illustrative calculation. Review the assumptions and any limitations displayed in this tool; validate important decisions against an appropriate independent source.
