What is 4/36 plus 2/3? (Answer: 7/9)

Exact Answer

==================================================
Problem: What is 4/36 plus 2/3?
Formula / Expression: 4/36 + 2/3
Final Answer: 7/9
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
Notice that 36 is an exact multiple of 3 (3 × 12 = 36). The Least Common Denominator (LCD) is simply 36, meaning we only need to scale one fraction.
Working: LCD(36, 3) = 36

Step 2: Convert to Equivalent Fractions with Common Denominator 36
Multiply the numerator and denominator of 4/36 by 1, and multiply the numerator and denominator of 2/3 by 12 so both fractions share the common base 36.
Working: 4 × 1/36 × 1 = 4/36 and 2 × 12/3 × 12 = 24/36

Step 3: Add the Numerators
Now add the numerators (4 + 24 = 28) and keep the common denominator 36 unchanged.
Working: 4 + 24/36 = 28/36

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 28 and 36, which is 4. Divide both the numerator and denominator by 4.
Working: 28 ÷ 4/36 ÷ 4 = 7/9

Step 5: Decimal & Percentage Representation
Dividing the numerator 7 by denominator 9 produces a repeating decimal (approximately 0.777778, or 77.7778%).
Working: 7 ÷ 9 = 0.777778 (77.7778%)

Key Values:
- Simplified Fraction: 7/9
- Mixed Number Form: 7/9
- Decimal Value: 0.777778
- Percentage: 77.7778%
