Exact Answer

==================================================
Problem: What is 2/7 plus 7/22?
Formula / Expression: 2/7 + 7/22
Final Answer: 93/154
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 7 and 22 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 7 × 22 = 154.
Working: LCD(7, 22) = 154

Step 2: Convert to Equivalent Fractions with Common Denominator 154
Multiply the numerator and denominator of 2/7 by 22, and multiply the numerator and denominator of 7/22 by 7 so both fractions share the common base 154.
Working: 2 × 22/7 × 22 = 44/154 and 7 × 7/22 × 7 = 49/154

Step 3: Add the Numerators
Now add the numerators (44 + 49 = 93) and keep the common denominator 154 unchanged.
Working: 44 + 49/154 = 93/154

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 93 and 154 is 1, confirming that 93/154 cannot be reduced further—it is already in its simplest irreducible form.
Working: 93/154

Step 5: Decimal & Percentage Representation
Dividing the numerator 93 by denominator 154 produces a repeating decimal (approximately 0.603896, or 60.3896%).
Working: 93 ÷ 154 = 0.603896 (60.3896%)

Key Values:
- Simplified Fraction: 93/154
- Mixed Number Form: 93/154
- Decimal Value: 0.603896
- Percentage: 60.3896%

Step-by-Step Solution: 2/7 + 7/22

Step 1

Find the Least Common Denominator (LCD)

The denominators 7 and 22 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 7 × 22 = 154.

LCD(7, 22) = 154

Step 2

Convert to Equivalent Fractions with Common Denominator 154

Multiply the numerator and denominator of 2/7 by 22, and multiply the numerator and denominator of 7/22 by 7 so both fractions share the common base 154.

2 × 22/7 × 22 = 44/154 and 7 × 7/22 × 7 = 49/154

Step 3

Add the Numerators

Now add the numerators (44 + 49 = 93) and keep the common denominator 154 unchanged.

44 + 49/154 = 93/154

Step 4

Check if the Fraction Can Be Simplified

The Greatest Common Divisor (GCD) of 93 and 154 is 1, confirming that 93/154 cannot be reduced further—it is already in its simplest irreducible form.

93/154

Step 5

Decimal & Percentage Representation
