What is 3/36 plus 2/7? (Answer: 31/84)

Exact Answer

==================================================
Problem: What is 3/36 plus 2/7?
Formula / Expression: 3/36 + 2/7
Final Answer: 31/84
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 36 and 7 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 36 × 7 = 252.
Working: LCD(36, 7) = 252

Step 2: Convert to Equivalent Fractions with Common Denominator 252
Multiply the numerator and denominator of 3/36 by 7, and multiply the numerator and denominator of 2/7 by 36 so both fractions share the common base 252.
Working: 3 × 7/36 × 7 = 21/252 and 2 × 36/7 × 36 = 72/252

Step 3: Add the Numerators
Now add the numerators (21 + 72 = 93) and keep the common denominator 252 unchanged.
Working: 21 + 72/252 = 93/252

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 93 and 252, which is 3. Divide both the numerator and denominator by 3.
Working: 93 ÷ 3/252 ÷ 3 = 31/84

Step 5: Decimal & Percentage Representation
Dividing the numerator 31 by denominator 84 produces a repeating decimal (approximately 0.369048, or 36.9048%).
Working: 31 ÷ 84 = 0.369048 (36.9048%)

Key Values:
- Simplified Fraction: 31/84
- Mixed Number Form: 31/84
- Decimal Value: 0.369048
- Percentage: 36.9048%

Step-by-Step Solution: 3/36 + 2/7

Step 1

Find the Least Common Denominator (LCD)

The denominators 36 and 7 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 36 × 7 = 252.

LCD(36, 7) = 252

Step 2

Convert to Equivalent Fractions with Common Denominator 252

Multiply the numerator and denominator of 3/36 by 7, and multiply the numerator and denominator of 2/7 by 36 so both fractions share the common base 252.

3 × 7/36 × 7 = 21/252 and 2 × 36/7 × 36 = 72/252

Step 3

Add the Numerators

Now add the numerators (21 + 72 = 93) and keep the common denominator 252 unchanged.

21 + 72/252 = 93/252

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 93 and 252, which is 3. Divide both the numerator and denominator by 3.

93 ÷ 3/252 ÷ 3 = 31/84

Step 5

Decimal & Percentage Representation

Dividing the numerator 31 by denominator 84 produces a repeating decimal (approximately 0.369048, or 36.9048%).

31 ÷ 84 = 0.369048 (36.9048%)
