What is 2/30 plus 3/4? (Answer: 49/60)

Exact Answer

==================================================
Problem: What is 2/30 plus 3/4?
Formula / Expression: 2/30 + 3/4
Final Answer: 49/60
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 30 and 4 share a common factor (GCD = 2). Finding their Least Common Multiple gives an LCD of 60 (which is smaller than their product 30 × 4 = 120, keeping the calculation simpler).
Working: LCD(30, 4) = 60

Step 2: Convert to Equivalent Fractions with Common Denominator 60
Multiply the numerator and denominator of 2/30 by 2, and multiply the numerator and denominator of 3/4 by 15 so both fractions share the common base 60.
Working: 2 × 2/30 × 2 = 4/60 and 3 × 15/4 × 15 = 45/60

Step 3: Add the Numerators
Now add the numerators (4 + 45 = 49) and keep the common denominator 60 unchanged.
Working: 4 + 45/60 = 49/60

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 49 and 60 is 1, confirming that 49/60 cannot be reduced further—it is already in its simplest irreducible form.
Working: 49/60

Step 5: Decimal & Percentage Representation
Dividing the numerator 49 by denominator 60 produces a repeating decimal (approximately 0.816667, or 81.6667%).
Working: 49 ÷ 60 = 0.816667 (81.6667%)

Key Values:
- Simplified Fraction: 49/60
- Mixed Number Form: 49/60
- Decimal Value: 0.816667
- Percentage: 81.6667%

The denominators 30 and 4 share a common factor (GCD = 2). Finding their Least Common Multiple gives an LCD of 60 (which is smaller than their product 30 × 4 = 120, keeping the calculation simpler).

LCD(30, 4) = 60

Step 2

Convert to Equivalent Fractions with Common Denominator 60

Multiply the numerator and denominator of 2/30 by 2, and multiply the numerator and denominator of 3/4 by 15 so both fractions share the common base 60.

2 × 2/30 × 2 = 4/60 and 3 × 15/4 × 15 = 45/60

Step 3

Add the Numerators

Now add the numerators (4 + 45 = 49) and keep the common denominator 60 unchanged.

4 + 45/60 = 49/60

Step 4

Check if the Fraction Can Be Simplified

The Greatest Common Divisor (GCD) of 49 and 60 is 1, confirming that 49/60 cannot be reduced further—it is already in its simplest irreducible form.
