What is 1/16 plus 2/3? (Answer: 35/48)

Exact Answer

==================================================
Problem: What is 1/16 plus 2/3?
Formula / Expression: 1/16 + 2/3
Final Answer: 35/48
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 16 and 3 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 16 × 3 = 48.
Working: LCD(16, 3) = 48

Step 2: Convert to Equivalent Fractions with Common Denominator 48
Multiply the numerator and denominator of 1/16 by 3, and multiply the numerator and denominator of 2/3 by 16 so both fractions share the common base 48.
Working: 1 × 3/16 × 3 = 3/48 and 2 × 16/3 × 16 = 32/48

Step 3: Add the Numerators
Now add the numerators (3 + 32 = 35) and keep the common denominator 48 unchanged.
Working: 3 + 32/48 = 35/48

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 35 and 48 is 1, confirming that 35/48 cannot be reduced further—it is already in its simplest irreducible form.
Working: 35/48

Step 5: Decimal & Percentage Representation
Dividing the numerator 35 by denominator 48 produces a repeating decimal (approximately 0.729167, or 72.9167%).
Working: 35 ÷ 48 = 0.729167 (72.9167%)

Key Values:
- Simplified Fraction: 35/48
- Mixed Number Form: 35/48
- Decimal Value: 0.729167
- Percentage: 72.9167%

Step-by-Step Solution: 1/16 + 2/3

Step 1

Find the Least Common Denominator (LCD)

The denominators 16 and 3 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 16 × 3 = 48.

LCD(16, 3) = 48

Step 2

Convert to Equivalent Fractions with Common Denominator 48

Multiply the numerator and denominator of 1/16 by 3, and multiply the numerator and denominator of 2/3 by 16 so both fractions share the common base 48.

1 × 3/16 × 3 = 3/48 and 2 × 16/3 × 16 = 32/48

Step 3

Add the Numerators

Now add the numerators (3 + 32 = 35) and keep the common denominator 48 unchanged.

3 + 32/48 = 35/48

Step 4

Check if the Fraction Can Be Simplified

The Greatest Common Divisor (GCD) of 35 and 48 is 1, confirming that 35/48 cannot be reduced further—it is already in its simplest irreducible form.
