Formula Used in Adding Fractions Calculator

To understand how this calculator works, let’s break down the mathematical formulas.


1. Fraction Addition Formula

To add two fractions:

Formula:

ab+cd=(a×d)+(c×b)b×d\frac{a}{b} + \frac{c}{d} = \frac{(a \times d) + (c \times b)}{b \times d}ba​+dc​=b×d(a×d)+(c×b)​

Where:

  • a = numerator of first fraction
  • b = denominator of first fraction
  • c = numerator of second fraction
  • d = denominator of second fraction

2. Simplification Formula

After addition, the fraction is simplified using the Greatest Common Divisor (GCD).

Formula:

  • Find GCD of numerator and denominator
  • Divide both by GCD

numden÷GCD\frac{num}{den} \div GCDdennum​÷GCD


3. Decimal Conversion Formula

Formula:

Decimal=NumeratorDenominatorDecimal = \frac{Numerator}{Denominator}Decimal=DenominatorNumerator​


Step-by-Step Example of Adding Fractions

Let’s understand with a real example.

Example:

Add:

2/5 + 3/4


Step 1: Apply formula

(2×4)+(3×5)=8+15=23(2 \times 4) + (3 \times 5) = 8 + 15 = 23(2×4)+(3×5)=8+15=23Denominator=5×4=20Denominator = 5 \times 4 = 20Denominator=5×4=20

So:23/2023/2023/20


Step 2: Simplify fraction

GCD of 23 and 20 = 1

So fraction remains:

23/20


Step 3: Convert to decimal

23÷20=1.1523 ÷ 20 = 1.1523÷20=1.15


Final Answer:

Decimal1.1500

More Examples of Fraction Addition

Example 1:

1/3 + 1/6

  • Result = 3/6 + 1/6 = 4/6
  • Simplified = 2/3
  • Decimal = 0.6667

Example 2:

5/8 + 1/4

  • Convert: 1/4 = 2/8
  • Add: 5/8 + 2/8 = 7/8
  • Decimal = 0.8750

Example 3:

7/10 + 2/5

  • Convert: 2/5 = 4/10
  • Add: 7/10 + 4/10 = 11/10
  • Decimal = 1.1000
