Fraction Calculation Formulas
Below are the formulas used by the calculator.
Addition of Fractions
If denominators are different:
Formula
(a/b) + (c/d)
= (ad + bc) / bd
Example
1/4 + 2/3
= (1×3 + 2×4) / (4×3)
= (3 + 8)/12
=11/12
Subtraction of Fractions
Formula
(a/b) − (c/d)
= (ad − bc) / bd
Example
5/6 − 1/3
= (5×3 − 1×6)/18
=9/18
=1/2
Multiplication of Fractions
Formula
(a/b) × (c/d)
= ac/bd
Example
3/5 × 4/7
=12/35
Division of Fractions
Division is performed by multiplying by the reciprocal.
Formula
(a/b) ÷ (c/d)
= (a/b) × (d/c)
Example
2/5 ÷ 3/4
=2/5 × 4/3
=8/15
Simplifying Fractions
After completing any operation, the calculator simplifies the result.
A fraction is simplified by dividing both numerator and denominator by their Greatest Common Divisor (GCD).
Example
18/24
Greatest Common Divisor = 6
18 ÷ 6 = 3
24 ÷ 6 = 4
Final Answer:
3/4
Converting Fractions to Decimals
Fractions are converted into decimals by dividing the numerator by the denominator.
Formula
Decimal = Numerator ÷ Denominator
Example
7/8
=0.875
This conversion is useful for financial calculations, measurements, and engineering applications.
Converting Improper Fractions into Mixed Numbers
When the numerator is greater than the denominator, the calculator converts the answer into a mixed number.
Formula
Whole Number = Numerator ÷ Denominator
Remainder = Numerator mod Denominator
Mixed Number
Whole Number + Remainder/Denominator
Example
17/5
Whole Number = 3
Remainder = 2
Mixed Number
3 2/5
Example Calculation
Suppose you want to calculate:
3/4 + 5/8
Step 1
Common denominator:
32
Step 2
Multiply numerators.
3 × 8 = 24
5 × 4 = 20
Step 3
Add
24 + 20 = 44
Result
44/32
Step 4
Simplify
44/32
=11/8
Step 5
Convert
Decimal
11 ÷ 8
=1.375
Mixed Number
1 3/8
Final Results:
- Simplified Fraction = 11/8
- Decimal = 1.375
- Mixed Number = 1 3/8
