What is 7/22 plus 4/8? (Answer: 9/11)

Exact Answer

==================================================
Problem: What is 7/22 plus 4/8?
Formula / Expression: 7/22 + 4/8
Final Answer: 9/11
==================================================

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 7/22 by 4, and multiply the numerator and denominator of 4/8 by 11 so both fractions share the common base 88.
Working: 7 × 4/22 × 4 = 28/88 and 4 × 11/8 × 11 = 44/88

Step 3: Add the Numerators
Now add the numerators (28 + 44 = 72) and keep the common denominator 88 unchanged.
Working: 28 + 44/88 = 72/88

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 72 and 88, which is 8. Divide both the numerator and denominator by 8.
Working: 72 ÷ 8/88 ÷ 8 = 9/11

Step 5: Decimal & Percentage Representation
Dividing the numerator 9 by denominator 11 produces a repeating decimal (approximately 0.818182, or 81.8182%).
Working: 9 ÷ 11 = 0.818182 (81.8182%)

Key Values:
- Simplified Fraction: 9/11
- Mixed Number Form: 9/11
- Decimal Value: 0.818182
- Percentage: 81.8182%

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).

LCD(22, 8) = 88

Step 2

Convert to Equivalent Fractions with Common Denominator 88

Multiply the numerator and denominator of 7/22 by 4, and multiply the numerator and denominator of 4/8 by 11 so both fractions share the common base 88.

7 × 4/22 × 4 = 28/88 and 4 × 11/8 × 11 = 44/88

Step 3

Add the Numerators

Now add the numerators (28 + 44 = 72) and keep the common denominator 88 unchanged.

28 + 44/88 = 72/88

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 72 and 88, which is 8. Divide both the numerator and denominator by 8.

72 ÷ 8/88 ÷ 8 = 9/11

Step 5
