What is 4/50 plus 2/9? (Answer: 68/225)

Exact Answer

==================================================
Problem: What is 4/50 plus 2/9?
Formula / Expression: 4/50 + 2/9
Final Answer: 68/225
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 50 and 9 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 50 × 9 = 450.
Working: LCD(50, 9) = 450

Step 2: Convert to Equivalent Fractions with Common Denominator 450
Multiply the numerator and denominator of 4/50 by 9, and multiply the numerator and denominator of 2/9 by 50 so both fractions share the common base 450.
Working: 4 × 9/50 × 9 = 36/450 and 2 × 50/9 × 50 = 100/450

Step 3: Add the Numerators
Now add the numerators (36 + 100 = 136) and keep the common denominator 450 unchanged.
Working: 36 + 100/450 = 136/450

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 136 and 450, which is 2. Divide both the numerator and denominator by 2.
Working: 136 ÷ 2/450 ÷ 2 = 68/225

Step 5: Decimal & Percentage Representation
Dividing the numerator 68 by denominator 225 produces a repeating decimal (approximately 0.302222, or 30.2222%).
Working: 68 ÷ 225 = 0.302222 (30.2222%)

Key Values:
- Simplified Fraction: 68/225
- Mixed Number Form: 68/225
- Decimal Value: 0.302222
- Percentage: 30.2222%

Step-by-Step Solution: 4/50 + 2/9

Step 1

Find the Least Common Denominator (LCD)

The denominators 50 and 9 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 50 × 9 = 450.

LCD(50, 9) = 450

Step 2

Convert to Equivalent Fractions with Common Denominator 450

Multiply the numerator and denominator of 4/50 by 9, and multiply the numerator and denominator of 2/9 by 50 so both fractions share the common base 450.

4 × 9/50 × 9 = 36/450 and 2 × 50/9 × 50 = 100/450

Step 3

Add the Numerators

Now add the numerators (36 + 100 = 136) and keep the common denominator 450 unchanged.

36 + 100/450 = 136/450

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 136 and 450, which is 2. Divide both the numerator and denominator by 2.

136 ÷ 2/450 ÷ 2 = 68/225

Step 5

Decimal & Percentage Representation

Dividing the numerator 68 by denominator 225 produces a repeating decimal (approximately 0.302222, or 30.2222%).

68 ÷ 225 = 0.302222 (30.2222%)
