What is 4/52 plus 7/13? (Answer: 8/13)

Exact Answer

==================================================
Problem: What is 4/52 plus 7/13?
Formula / Expression: 4/52 + 7/13
Final Answer: 8/13
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
Notice that 52 is an exact multiple of 13 (13 × 4 = 52). The Least Common Denominator (LCD) is simply 52, meaning we only need to scale one fraction.
Working: LCD(52, 13) = 52

Step 2: Convert to Equivalent Fractions with Common Denominator 52
Multiply the numerator and denominator of 4/52 by 1, and multiply the numerator and denominator of 7/13 by 4 so both fractions share the common base 52.
Working: 4 × 1/52 × 1 = 4/52 and 7 × 4/13 × 4 = 28/52

Step 3: Add the Numerators
Now add the numerators (4 + 28 = 32) and keep the common denominator 52 unchanged.
Working: 4 + 28/52 = 32/52

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 32 and 52, which is 4. Divide both the numerator and denominator by 4.
Working: 32 ÷ 4/52 ÷ 4 = 8/13

Step 5: Decimal & Percentage Representation
Dividing the numerator 8 by denominator 13 produces a repeating decimal (approximately 0.615385, or 61.5385%).
Working: 8 ÷ 13 = 0.615385 (61.5385%)

Key Values:
- Simplified Fraction: 8/13
- Mixed Number Form: 8/13
- Decimal Value: 0.615385
- Percentage: 61.5385%

Find the Least Common Denominator (LCD)

Notice that 52 is an exact multiple of 13 (13 × 4 = 52). The Least Common Denominator (LCD) is simply 52, meaning we only need to scale one fraction.

LCD(52, 13) = 52

Step 2

Convert to Equivalent Fractions with Common Denominator 52

Multiply the numerator and denominator of 4/52 by 1, and multiply the numerator and denominator of 7/13 by 4 so both fractions share the common base 52.

4 × 1/52 × 1 = 4/52 and 7 × 4/13 × 4 = 28/52

Step 3

Add the Numerators

Now add the numerators (4 + 28 = 32) and keep the common denominator 52 unchanged.

4 + 28/52 = 32/52

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 32 and 52, which is 4. Divide both the numerator and denominator by 4.

32 ÷ 4/52 ÷ 4 = 8/13

Step 5
