What is 2/14 plus 3/8? (Answer: 29/56)

Exact Answer

==================================================
Problem: What is 2/14 plus 3/8?
Formula / Expression: 2/14 + 3/8
Final Answer: 29/56
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 14 and 8 share a common factor (GCD = 2). Finding their Least Common Multiple gives an LCD of 56 (which is smaller than their product 14 × 8 = 112, keeping the calculation simpler).
Working: LCD(14, 8) = 56

Step 2: Convert to Equivalent Fractions with Common Denominator 56
Multiply the numerator and denominator of 2/14 by 4, and multiply the numerator and denominator of 3/8 by 7 so both fractions share the common base 56.
Working: 2 × 4/14 × 4 = 8/56 and 3 × 7/8 × 7 = 21/56

Step 3: Add the Numerators
Now add the numerators (8 + 21 = 29) and keep the common denominator 56 unchanged.
Working: 8 + 21/56 = 29/56

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 29 and 56 is 1, confirming that 29/56 cannot be reduced further—it is already in its simplest irreducible form.
Working: 29/56

Step 5: Decimal & Percentage Representation
Dividing the numerator 29 by denominator 56 produces a repeating decimal (approximately 0.517857, or 51.7857%).
Working: 29 ÷ 56 = 0.517857 (51.7857%)

Key Values:
- Simplified Fraction: 29/56
- Mixed Number Form: 29/56
- Decimal Value: 0.517857
- Percentage: 51.7857%

The denominators 14 and 8 share a common factor (GCD = 2). Finding their Least Common Multiple gives an LCD of 56 (which is smaller than their product 14 × 8 = 112, keeping the calculation simpler).

LCD(14, 8) = 56

Step 2

Convert to Equivalent Fractions with Common Denominator 56

Multiply the numerator and denominator of 2/14 by 4, and multiply the numerator and denominator of 3/8 by 7 so both fractions share the common base 56.

2 × 4/14 × 4 = 8/56 and 3 × 7/8 × 7 = 21/56

Step 3

Add the Numerators

Now add the numerators (8 + 21 = 29) and keep the common denominator 56 unchanged.

8 + 21/56 = 29/56

Step 4

Check if the Fraction Can Be Simplified

The Greatest Common Divisor (GCD) of 29 and 56 is 1, confirming that 29/56 cannot be reduced further—it is already in its simplest irreducible form.
