What is 2/22 plus 5/8? (Answer: 63/88)

Exact Answer

==================================================
Problem: What is 2/22 plus 5/8?
Formula / Expression: 2/22 + 5/8
Final Answer: 63/88
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 22 and 8 share a common factor (GCD = 2). Finding their Least Common Multiple gives an LCD of 88 (which is smaller than their product 22 × 8 = 176, keeping the calculation simpler).
Working: LCD(22, 8) = 88

Step 2: Convert to Equivalent Fractions with Common Denominator 88
Multiply the numerator and denominator of 2/22 by 4, and multiply the numerator and denominator of 5/8 by 11 so both fractions share the common base 88.
Working: 2 × 4/22 × 4 = 8/88 and 5 × 11/8 × 11 = 55/88

Step 3: Add the Numerators
Now add the numerators (8 + 55 = 63) and keep the common denominator 88 unchanged.
Working: 8 + 55/88 = 63/88

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 63 and 88 is 1, confirming that 63/88 cannot be reduced further—it is already in its simplest irreducible form.
Working: 63/88

Step 5: Decimal & Percentage Representation
Dividing the numerator 63 by denominator 88 produces a repeating decimal (approximately 0.715909, or 71.5909%).
Working: 63 ÷ 88 = 0.715909 (71.5909%)

Key Values:
- Simplified Fraction: 63/88
- Mixed Number Form: 63/88
- Decimal Value: 0.715909
