What is 2/10 plus 5/6? (Answer: 31/30)

Exact Answer

==================================================
Problem: What is 2/10 plus 5/6?
Formula / Expression: 2/10 + 5/6
Final Answer: 1 1/30 (31/30)
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 10 and 6 share a common factor (GCD = 2). Finding their Least Common Multiple gives an LCD of 30 (which is smaller than their product 10 × 6 = 60, keeping the calculation simpler).
Working: LCD(10, 6) = 30

Step 2: Convert to Equivalent Fractions with Common Denominator 30
Multiply the numerator and denominator of 2/10 by 3, and multiply the numerator and denominator of 5/6 by 5 so both fractions share the common base 30.
Working: 2 × 3/10 × 3 = 6/30 and 5 × 5/6 × 5 = 25/30

Step 3: Add the Numerators
Now add the numerators (6 + 25 = 31) and keep the common denominator 30 unchanged.
Working: 6 + 25/30 = 31/30

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 31 and 30 is 1, confirming that 31/30 cannot be reduced further—it is already in its simplest irreducible form.
Working: 31/30

Step 5: Convert Improper Fraction to a Mixed Number
Since the numerator (31) is greater than the denominator (30), divide 31 by 30: it goes in 1 whole time(s) with a remainder of 1, giving the mixed number 1 1/30.
Working: 31/30 = 1 1/30

Step 6: Decimal & Percentage Representation
Dividing the numerator 31 by denominator 30 produces a repeating decimal (approximately 1.033333, or 103.3333%).
Working: 31 ÷ 30 = 1.033333 (103.3333%)

Key Values:
- Simplified Fraction: 31/30
- Mixed Number Form: 1 1/30
- Decimal Value: 1.033333
- Percentage: 103.3333%

Step-by-Step Solution: 2/10 + 5/6

Step 1

Find the Least Common Denominator (LCD)

The denominators 10 and 6 share a common factor (GCD = 2). Finding their Least Common Multiple gives an LCD of 30 (which is smaller than their product 10 × 6 = 60, keeping the calculation simpler).

LCD(10, 6) = 30

Step 2

Convert to Equivalent Fractions with Common Denominator 30

Multiply the numerator and denominator of 2/10 by 3, and multiply the numerator and denominator of 5/6 by 5 so both fractions share the common base 30.

2 × 3/10 × 3 = 6/30 and 5 × 5/6 × 5 = 25/30

Step 3

Add the Numerators

Now add the numerators (6 + 25 = 31) and keep the common denominator 30 unchanged.

6 + 25/30 = 31/30

Step 4

Check if the Fraction Can Be Simplified

The Greatest Common Divisor (GCD) of 31 and 30 is 1, confirming that 31/30 cannot be reduced further—it is already in its simplest irreducible form.

31/30

Step 5

Convert Improper Fraction to a Mixed Number

Since the numerator (31) is greater than the denominator (30), divide 31 by 30: it goes in 1 whole time(s) with a remainder of 1, giving the mixed number 1 1/30.

31/30 = 11/30

Step 6

Decimal & Percentage Representation

Dividing the numerator 31 by denominator 30 produces a repeating decimal (approximately 1.033333, or 103.3333%).

31 ÷ 30 = 1.033333 (103.3333%)
