Understanding Fraction Formulas

To fully understand how the calculator works, it is important to know the basic formulas behind fraction operations.


1. Addition of Fractions

When denominators are different:ab+cd=ad+bcbd\frac{a}{b} + \frac{c}{d} = \frac{ad + bc}{bd}ba​+dc​=bdad+bc​

This means:

  • Multiply numerator of first by denominator of second
  • Multiply numerator of second by denominator of first
  • Add results
  • Multiply denominators

2. Subtraction of Fractions

abcd=adbcbd\frac{a}{b} – \frac{c}{d} = \frac{ad – bc}{bd}ba​−dc​=bdad−bc​

Same process as addition, but subtract numerators instead.


3. Multiplication of Fractions

ab×cd=acbd\frac{a}{b} \times \frac{c}{d} = \frac{ac}{bd}ba​×dc​=bdac​

Multiply numerators together and denominators together.


4. Division of Fractions

ab÷cd=a×db×c\frac{a}{b} \div \frac{c}{d} = \frac{a \times d}{b \times c}ba​÷dc​=b×ca×d​

Multiply first fraction by reciprocal of second fraction.


Simplifying Fractions

After performing calculations, results are simplified using the Greatest Common Divisor (GCD).

Simplification Formula:

ab=a÷gcd(a,b)b÷gcd(a,b)\frac{a}{b} = \frac{a \div gcd(a,b)}{b \div gcd(a,b)}ba​=b÷gcd(a,b)a÷gcd(a,b)​

Where:

  • GCD is the largest number that divides both numerator and denominator

This ensures the fraction is in its lowest form.


Example Calculations

Example 1: Addition

23+14\frac{2}{3} + \frac{1}{4}32​+41​

Step-by-step:

  • (2 × 4) + (1 × 3) = 8 + 3 = 11
  • Denominator = 3 × 4 = 12

Final Answer:1112\frac{11}{12}1211​


Example 2: Subtraction

5613\frac{5}{6} – \frac{1}{3}65​−31​

  • (5 × 3) – (1 × 6) = 15 – 6 = 9
  • Denominator = 6 × 3 = 18

Simplify:918=12\frac{9}{18} = \frac{1}{2}189​=21​


Example 3: Multiplication

35×27\frac{3}{5} \times \frac{2}{7}53​×72​

  • Numerator = 3 × 2 = 6
  • Denominator = 5 × 7 = 35

Final Answer:635\frac{6}{35}356​


Example 4: Division

49÷23\frac{4}{9} \div \frac{2}{3}94​÷32​

  • Multiply by reciprocal: 4/9 × 3/2
  • Numerator = 12
  • Denominator = 18

Simplify:1218=23\frac{12}{18} = \frac{2}{3}1812​=32​
