What is 3/16 plus 1/2? (Answer: 11/16)

Exact Answer

==================================================
Problem: What is 3/16 plus 1/2?
Formula / Expression: 3/16 + 1/2
Final Answer: 11/16
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
Notice that 16 is an exact multiple of 2 (2 × 8 = 16). The Least Common Denominator (LCD) is simply 16, meaning we only need to scale one fraction.
Working: LCD(16, 2) = 16

Step 2: Convert to Equivalent Fractions with Common Denominator 16
Multiply the numerator and denominator of 3/16 by 1, and multiply the numerator and denominator of 1/2 by 8 so both fractions share the common base 16.
Working: 3 × 1/16 × 1 = 3/16 and 1 × 8/2 × 8 = 8/16

Step 3: Add the Numerators
Now add the numerators (3 + 8 = 11) and keep the common denominator 16 unchanged.
Working: 3 + 8/16 = 11/16

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 11 and 16 is 1, confirming that 11/16 cannot be reduced further—it is already in its simplest irreducible form.
Working: 11/16

Step 5: Decimal & Percentage Representation
Dividing the numerator 11 by denominator 16 yields an exact terminating decimal of 0.6875 (or 68.75%).
Working: 11 ÷ 16 = 0.6875 (68.75%)

Key Values:
- Simplified Fraction: 11/16
- Mixed Number Form: 11/16
- Decimal Value: 0.6875
- Percentage: 68.75%
