Exact Answer

==================================================
Problem: What is 3/22 plus 7/49?
Formula / Expression: 3/22 + 7/49
Final Answer: 43/154
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 22 and 49 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 22 × 49 = 1078.
Working: LCD(22, 49) = 1078

Step 2: Convert to Equivalent Fractions with Common Denominator 1078
Multiply the numerator and denominator of 3/22 by 49, and multiply the numerator and denominator of 7/49 by 22 so both fractions share the common base 1078.
Working: 3 × 49/22 × 49 = 147/1078 and 7 × 22/49 × 22 = 154/1078

Step 3: Add the Numerators
Now add the numerators (147 + 154 = 301) and keep the common denominator 1078 unchanged.
Working: 147 + 154/1078 = 301/1078

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 301 and 1078, which is 7. Divide both the numerator and denominator by 7.
Working: 301 ÷ 7/1078 ÷ 7 = 43/154

Step 5: Decimal & Percentage Representation
Dividing the numerator 43 by denominator 154 produces a repeating decimal (approximately 0.279221, or 27.9221%).
Working: 43 ÷ 154 = 0.279221 (27.9221%)

Key Values:
- Simplified Fraction: 43/154
- Mixed Number Form: 43/154
- Decimal Value: 0.279221
- Percentage: 27.9221%

Step-by-Step Solution: 3/22 + 7/49

Step 1

Find the Least Common Denominator (LCD)

The denominators 22 and 49 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 22 × 49 = 1078.

LCD(22, 49) = 1078

Step 2

Convert to Equivalent Fractions with Common Denominator 1078

Multiply the numerator and denominator of 3/22 by 49, and multiply the numerator and denominator of 7/49 by 22 so both fractions share the common base 1078.

3 × 49/22 × 49 = 147/1078 and 7 × 22/49 × 22 = 154/1078

Step 3

Add the Numerators

Now add the numerators (147 + 154 = 301) and keep the common denominator 1078 unchanged.

147 + 154/1078 = 301/1078

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 301 and 1078, which is 7. Divide both the numerator and denominator by 7.

301 ÷ 7/1078 ÷ 7 = 43/154

Step 5

Decimal & Percentage Representation

Dividing the numerator 43 by denominator 154 produces a repeating decimal (approximately 0.279221, or 27.9221%).

43 ÷ 154 = 0.279221 (27.9221%)
