What is 3/16 plus 2/7? (Answer: 53/112)

Exact Answer

==================================================
Problem: What is 3/16 plus 2/7?
Formula / Expression: 3/16 + 2/7
Final Answer: 53/112
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 16 and 7 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 16 × 7 = 112.
Working: LCD(16, 7) = 112

Step 2: Convert to Equivalent Fractions with Common Denominator 112
Multiply the numerator and denominator of 3/16 by 7, and multiply the numerator and denominator of 2/7 by 16 so both fractions share the common base 112.
Working: 3 × 7/16 × 7 = 21/112 and 2 × 16/7 × 16 = 32/112

Step 3: Add the Numerators
Now add the numerators (21 + 32 = 53) and keep the common denominator 112 unchanged.
Working: 21 + 32/112 = 53/112

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 53 and 112 is 1, confirming that 53/112 cannot be reduced further—it is already in its simplest irreducible form.
Working: 53/112

Step 5: Decimal & Percentage Representation
Dividing the numerator 53 by denominator 112 produces a repeating decimal (approximately 0.473214, or 47.3214%).
Working: 53 ÷ 112 = 0.473214 (47.3214%)

Key Values:
- Simplified Fraction: 53/112
- Mixed Number Form: 53/112
- Decimal Value: 0.473214
- Percentage: 47.3214%

Step-by-Step Solution: 3/16 + 2/7

Step 1

Find the Least Common Denominator (LCD)

The denominators 16 and 7 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 16 × 7 = 112.

LCD(16, 7) = 112

Step 2

Convert to Equivalent Fractions with Common Denominator 112

Multiply the numerator and denominator of 3/16 by 7, and multiply the numerator and denominator of 2/7 by 16 so both fractions share the common base 112.

3 × 7/16 × 7 = 21/112 and 2 × 16/7 × 16 = 32/112

Step 3

Add the Numerators

Now add the numerators (21 + 32 = 53) and keep the common denominator 112 unchanged.

21 + 32/112 = 53/112

Step 4

Check if the Fraction Can Be Simplified

The Greatest Common Divisor (GCD) of 53 and 112 is 1, confirming that 53/112 cannot be reduced further—it is already in its simplest irreducible form.

53/112

Step 5

Decimal & Percentage Representation
