What is 2/8 plus 11/22? (Answer: 3/4)

Exact Answer

==================================================
Problem: What is 2/8 plus 11/22?
Formula / Expression: 2/8 + 11/22
Final Answer: 3/4
==================================================

Step-by-Step Solution:

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

Step 2: Convert to Equivalent Fractions with Common Denominator 88
Multiply the numerator and denominator of 2/8 by 11, and multiply the numerator and denominator of 11/22 by 4 so both fractions share the common base 88.
Working: 2 × 11/8 × 11 = 22/88 and 11 × 4/22 × 4 = 44/88

Step 3: Add the Numerators
Now add the numerators (22 + 44 = 66) and keep the common denominator 88 unchanged.
Working: 22 + 44/88 = 66/88

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 66 and 88, which is 22. Divide both the numerator and denominator by 22.
Working: 66 ÷ 22/88 ÷ 22 = 3/4

Step 5: Decimal & Percentage Representation
Dividing the numerator 3 by denominator 4 yields an exact terminating decimal of 0.75 (or 75%).
Working: 3 ÷ 4 = 0.75 (75%)

Key Values:
- Simplified Fraction: 3/4
- Mixed Number Form: 3/4
- Decimal Value: 0.75
- Percentage: 75%
