What is 4/22 plus 3/8? (Answer: 49/88)

Exact Answer

==================================================
Problem: What is 4/22 plus 3/8?
Formula / Expression: 4/22 + 3/8
Final Answer: 49/88
==================================================

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 4/22 by 4, and multiply the numerator and denominator of 3/8 by 11 so both fractions share the common base 88.
Working: 4 × 4/22 × 4 = 16/88 and 3 × 11/8 × 11 = 33/88

Step 3: Add the Numerators
Now add the numerators (16 + 33 = 49) and keep the common denominator 88 unchanged.
Working: 16 + 33/88 = 49/88

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 49 and 88 is 1, confirming that 49/88 cannot be reduced further—it is already in its simplest irreducible form.
Working: 49/88

Step 5: Decimal & Percentage Representation
Dividing the numerator 49 by denominator 88 produces a repeating decimal (approximately 0.556818, or 55.6818%).
Working: 49 ÷ 88 = 0.556818 (55.6818%)

Key Values:
- Simplified Fraction: 49/88
- Mixed Number Form: 49/88
- Decimal Value: 0.556818
