Exact Answer

==================================================
Problem: What is 8/56 plus 3/13?
Formula / Expression: 8/56 + 3/13
Final Answer: 34/91
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 56 and 13 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 56 × 13 = 728.
Working: LCD(56, 13) = 728

Step 2: Convert to Equivalent Fractions with Common Denominator 728
Multiply the numerator and denominator of 8/56 by 13, and multiply the numerator and denominator of 3/13 by 56 so both fractions share the common base 728.
Working: 8 × 13/56 × 13 = 104/728 and 3 × 56/13 × 56 = 168/728

Step 3: Add the Numerators
Now add the numerators (104 + 168 = 272) and keep the common denominator 728 unchanged.
Working: 104 + 168/728 = 272/728

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 272 and 728, which is 8. Divide both the numerator and denominator by 8.
Working: 272 ÷ 8/728 ÷ 8 = 34/91

Step 5: Decimal & Percentage Representation
Dividing the numerator 34 by denominator 91 produces a repeating decimal (approximately 0.373626, or 37.3626%).
Working: 34 ÷ 91 = 0.373626 (37.3626%)

Key Values:
- Simplified Fraction: 34/91
- Mixed Number Form: 34/91
- Decimal Value: 0.373626
- Percentage: 37.3626%

Step-by-Step Solution: 8/56 + 3/13

Step 1

Find the Least Common Denominator (LCD)

The denominators 56 and 13 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 56 × 13 = 728.

LCD(56, 13) = 728

Step 2

Convert to Equivalent Fractions with Common Denominator 728

Multiply the numerator and denominator of 8/56 by 13, and multiply the numerator and denominator of 3/13 by 56 so both fractions share the common base 728.

8 × 13/56 × 13 = 104/728 and 3 × 56/13 × 56 = 168/728

Step 3

Add the Numerators

Now add the numerators (104 + 168 = 272) and keep the common denominator 728 unchanged.

104 + 168/728 = 272/728

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 272 and 728, which is 8. Divide both the numerator and denominator by 8.

272 ÷ 8/728 ÷ 8 = 34/91

Step 5

Decimal & Percentage Representation

Dividing the numerator 34 by denominator 91 produces a repeating decimal (approximately 0.373626, or 37.3626%).

34 ÷ 91 = 0.373626 (37.3626%)
