Practical Example

Let’s walk through a real example.

Suppose you want to calculate: 14+23\frac{1}{4} + \frac{2}{3}41​+32​

Step 1: Enter the Fractions

• Numerator: 1, Denominator: 4
• Numerator: 2, Denominator: 3

Step 2: Click Calculate

Step 3: Results Displayed

• LCD = 12
• Convert:
  • 14=312\frac{1}{4} = \frac{3}{12}41​=123​
  • 23=812\frac{2}{3} = \frac{8}{12}32​=128​
• Sum of numerators = 3 + 8 = 11
• Final sum = 11/12
• Decimal result ≈ 0.916667

Answer: 14+23=1112\frac{1}{4} + \frac{2}{3} = \frac{11}{12}41​+32​=1211​

The calculator shows the step-by-step working, making it easy to understand how the solution was reached.
