What is 3/22 plus 4/8? (Answer: 7/11)

Exact Answer

==================================================
Problem: What is 3/22 plus 4/8?
Formula / Expression: 3/22 + 4/8
Final Answer: 7/11
==================================================

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 3/22 by 4, and multiply the numerator and denominator of 4/8 by 11 so both fractions share the common base 88.
Working: 3 × 4/22 × 4 = 12/88 and 4 × 11/8 × 11 = 44/88

Step 3: Add the Numerators
Now add the numerators (12 + 44 = 56) and keep the common denominator 88 unchanged.
Working: 12 + 44/88 = 56/88

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 56 and 88, which is 8. Divide both the numerator and denominator by 8.
Working: 56 ÷ 8/88 ÷ 8 = 7/11

Step 5: Decimal & Percentage Representation
Dividing the numerator 7 by denominator 11 produces a repeating decimal (approximately 0.636364, or 63.6364%).
Working: 7 ÷ 11 = 0.636364 (63.6364%)

Key Values:
- Simplified Fraction: 7/11
- Mixed Number Form: 7/11
- Decimal Value: 0.636364
- Percentage: 63.6364%

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 3/22 by 4, and multiply the numerator and denominator of 4/8 by 11 so both fractions share the common base 88.

3 × 4/22 × 4 = 12/88 and 4 × 11/8 × 11 = 44/88

Step 3

Add the Numerators

Now add the numerators (12 + 44 = 56) and keep the common denominator 88 unchanged.

12 + 44/88 = 56/88

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 56 and 88, which is 8. Divide both the numerator and denominator by 8.

56 ÷ 8/88 ÷ 8 = 7/11

Step 5

Decimal & Percentage Representation

Dividing the numerator 7 by denominator 11 produces a repeating decimal (approximately 0.636364, or 63.6364%).

7 ÷ 11 = 0.636364 (63.6364%)
