What is 2/16 plus 2/4? (Answer: 5/8)

Exact Answer

==================================================
Problem: What is 2/16 plus 2/4?
Formula / Expression: 2/16 + 2/4
Final Answer: 5/8
==================================================

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 2/16 by 1, and multiply the numerator and denominator of 2/4 by 4 so both fractions share the common base 16.
Working: 2 × 1/16 × 1 = 2/16 and 2 × 4/4 × 4 = 8/16

Step 3: Add the Numerators
Now add the numerators (2 + 8 = 10) and keep the common denominator 16 unchanged.
Working: 2 + 8/16 = 10/16

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 10 and 16, which is 2. Divide both the numerator and denominator by 2.
Working: 10 ÷ 2/16 ÷ 2 = 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: 2/16 + 2/4

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.

LCD(16, 4) = 16

Step 2

Convert to Equivalent Fractions with Common Denominator 16

Multiply the numerator and denominator of 2/16 by 1, and multiply the numerator and denominator of 2/4 by 4 so both fractions share the common base 16.

2 × 1/16 × 1 = 2/16 and 2 × 4/4 × 4 = 8/16

Step 3

Add the Numerators

Now add the numerators (2 + 8 = 10) and keep the common denominator 16 unchanged.

2 + 8/16 = 10/16

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 10 and 16, which is 2. Divide both the numerator and denominator by 2.

10 ÷ 2/16 ÷ 2 = 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%)
