Detail

READ FIRST: Fractions Calculator implements innovative User Interface without "=" operator: just enter Fractions into left/right input boxes and click on arithmetic Button ("+", "-", "x" or "÷"), thus saving the click. The result appears in calculation history beneath input boxes. Scroll it up/down or swipe to left or right in order to swap the input boxes content.

OVERVIEW

Fractions Calculator "Fractal MK-12" and MK-12P" (the latest Professional Edition) works on Regular (e.g. 2/3) and Improper (e.g. 4/3) Fractions, Mixed numbers (e.g. 1 /3/4), Decimals (e.g. 3.14) and Whole (like 12345) up to 10-digit length. It performs four standard Arithmetic operations (Add "+", Subtract "-", Multiply "x" and Divide "÷") and multiple function calculations:
• "R(f)" key to Reduce fraction to its Lowest Terms, e.g. 2/4 = 1/2
• "1/f" key to calculate the inverse Fraction, e.g. 2/3 (1/f) = 3/2
• "D" key to convert Fraction to Decimal, e.g. 3/5 = 0.6

Professional Edition (V 11.02 and later) also implements:
f² - square function
f->d Fraction to Decimal conversion
d->f Decimal to Fraction conversion
f->m Fraction to Mixed Number conversion
m->f Mixed Number to conversion

Professional Edition enables Memory operations allowing calculation history to be copied to app's internal memory and to system's Clipboard (see corresponding "scissors" and "paste" icons).

On-screen Keyboard contains several special keys:
• "/" to enter Fractions (e.g. 2/3, 54/7)
• "▭" to add blank space Mixed Numbers (e.g. 2 12/3)
• "." for entering Decimals (e.g. 3.14159)
• "±" to change the sign (e.g. from 3.14 to -3.14 and vice versa)
• "↑" to move the last calculation result into the first input box. This is a convenient feature for so-called "chain calculations" like: 1/2 + 3/5 + 4/7
• "◀" Backspace
• "C" to clear the content of input boxes and calculation history

Example 1. Reduce the Fraction 42/56 to the Lowest Terms
• Tap on the 1st input box and enter the Fraction 42/56 using digit keys and "/"
• Click on the "R(f)" key to get the result displayed as: 42/56 = 3/4

Example 2. Calculate: 3/4 + 1 2/5
• Tap on the 1st input box and enter the Fraction 3/4 using digit keys and "/"
• Tap on the 2nd box and enter Mixed Number 1 2/5 using digit keys, "▭" and "/"
• Click on the "+" key to get the result displayed as: 3/4 + 1 2/5 = 2 3/20

Example 3. Convert Mixed Number 2 3/20 to Decimal
• Tap on the 1st input box and enter Mixed Number 2 3/20 using digit keys, "▭" and "/"
• Click on the "D" key to get result displayed as: 2 3/20 = 2.15

Note: this conversion may result in so-called "repeating decimals", which are of infinite length, thus displayed as approximate rounded value, e.g: 2 1/6 = 2.1666667

Example 4. Calculate the inverse Fraction of 2 3/20
Step 1. Tap on 1st input box and enter Mixed Number 2 3/20 using digit keys, "▭" and "/"
Step 2. Click on the "1/f" key to get the result displayed as: 2 3/20 = 20/43

Cellphones and Tablets compatibility

This Fractions Calculator runs on any Android Cell Phones and Tablets w/OS version 5 and higher. For the best results, the screen size of at least 5.5" and screen resolution of 720 x 1280 and higher is recommended.
