What is 1/16 plus 2/4? (Answer: 9/16)

Exact Answer

==================================================
Problem: What is 1/16 plus 2/4?
Formula / Expression: 1/16 + 2/4
Final Answer: 9/16
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
Notice that 16 is an exact multiple of 4 (4 × 4 = 16). The Least Common Denominator (LCD) is simply 16, meaning we only need to scale one fraction.
Working: LCD(16, 4) = 16

Step 2: Convert to Equivalent Fractions with Common Denominator 16
Multiply the numerator and denominator of 1/16 by 1, and multiply the numerator and denominator of 2/4 by 4 so both fractions share the common base 16.
Working: 1 × 1/16 × 1 = 1/16 and 2 × 4/4 × 4 = 8/16

Step 3: Add the Numerators
Now add the numerators (1 + 8 = 9) and keep the common denominator 16 unchanged.
Working: 1 + 8/16 = 9/16

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 9 and 16 is 1, confirming that 9/16 cannot be reduced further—it is already in its simplest irreducible form.
Working: 9/16

Step 5: Decimal & Percentage Representation
Dividing the numerator 9 by denominator 16 yields an exact terminating decimal of 0.5625 (or 56.25%).
Working: 9 ÷ 16 = 0.5625 (56.25%)

Key Values:
- Simplified Fraction: 9/16
- Mixed Number Form: 9/16
- Decimal Value: 0.5625
- Percentage: 56.25%
