What is 1/8 plus 3/6? (Answer: 5/8)

Exact Answer

==================================================
Problem: What is 1/8 plus 3/6?
Formula / Expression: 1/8 + 3/6
Final Answer: 5/8
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 8 and 6 share a common factor (GCD = 2). Finding their Least Common Multiple gives an LCD of 24 (which is smaller than their product 8 × 6 = 48, keeping the calculation simpler).
Working: LCD(8, 6) = 24

Step 2: Convert to Equivalent Fractions with Common Denominator 24
Multiply the numerator and denominator of 1/8 by 3, and multiply the numerator and denominator of 3/6 by 4 so both fractions share the common base 24.
Working: 1 × 3/8 × 3 = 3/24 and 3 × 4/6 × 4 = 12/24

Step 3: Add the Numerators
Now add the numerators (3 + 12 = 15) and keep the common denominator 24 unchanged.
Working: 3 + 12/24 = 15/24

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 15 and 24, which is 3. Divide both the numerator and denominator by 3.
Working: 15 ÷ 3/24 ÷ 3 = 5/8

Step 5: Decimal & Percentage Representation
Dividing the numerator 5 by denominator 8 yields an exact terminating decimal of 0.625 (or 62.5%).
Working: 5 ÷ 8 = 0.625 (62.5%)

Key Values:
- Simplified Fraction: 5/8
- Mixed Number Form: 5/8
- Decimal Value: 0.625
- Percentage: 62.5%

Step-by-Step Solution: 1/8 + 3/6

Step 1

Find the Least Common Denominator (LCD)

The denominators 8 and 6 share a common factor (GCD = 2). Finding their Least Common Multiple gives an LCD of 24 (which is smaller than their product 8 × 6 = 48, keeping the calculation simpler).

LCD(8, 6) = 24

Step 2

Convert to Equivalent Fractions with Common Denominator 24

Multiply the numerator and denominator of 1/8 by 3, and multiply the numerator and denominator of 3/6 by 4 so both fractions share the common base 24.

1 × 3/8 × 3 = 3/24 and 3 × 4/6 × 4 = 12/24

Step 3

Add the Numerators

Now add the numerators (3 + 12 = 15) and keep the common denominator 24 unchanged.

3 + 12/24 = 15/24

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 15 and 24, which is 3. Divide both the numerator and denominator by 3.

15 ÷ 3/24 ÷ 3 = 5/8

Step 5

Decimal & Percentage Representation

Dividing the numerator 5 by denominator 8 yields an exact terminating decimal of 0.625 (or 62.5%).

5 ÷ 8 = 0.625 (62.5%)
