What is 2/10 plus 6/7? (Answer: 37/35)

Exact Answer

==================================================
Problem: What is 2/10 plus 6/7?
Formula / Expression: 2/10 + 6/7
Final Answer: 1 2/35 (37/35)
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 10 and 7 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 10 × 7 = 70.
Working: LCD(10, 7) = 70

Step 2: Convert to Equivalent Fractions with Common Denominator 70
Multiply the numerator and denominator of 2/10 by 7, and multiply the numerator and denominator of 6/7 by 10 so both fractions share the common base 70.
Working: 2 × 7/10 × 7 = 14/70 and 6 × 10/7 × 10 = 60/70

Step 3: Add the Numerators
Now add the numerators (14 + 60 = 74) and keep the common denominator 70 unchanged.
Working: 14 + 60/70 = 74/70

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 74 and 70, which is 2. Divide both the numerator and denominator by 2.
Working: 74 ÷ 2/70 ÷ 2 = 37/35

Step 5: Convert Improper Fraction to a Mixed Number
Since the numerator (37) is greater than the denominator (35), divide 37 by 35: it goes in 1 whole time(s) with a remainder of 2, giving the mixed number 1 2/35.
Working: 37/35 = 1 2/35

Step 6: Decimal & Percentage Representation
Dividing the numerator 37 by denominator 35 produces a repeating decimal (approximately 1.057143, or 105.7143%).
Working: 37 ÷ 35 = 1.057143 (105.7143%)

Key Values:
- Simplified Fraction: 37/35
- Mixed Number Form: 1 2/35
- Decimal Value: 1.057143
- Percentage: 105.7143%

Step-by-Step Solution: 2/10 + 6/7

Step 1

Find the Least Common Denominator (LCD)

The denominators 10 and 7 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 10 × 7 = 70.

LCD(10, 7) = 70

Step 2

Convert to Equivalent Fractions with Common Denominator 70

Multiply the numerator and denominator of 2/10 by 7, and multiply the numerator and denominator of 6/7 by 10 so both fractions share the common base 70.

2 × 7/10 × 7 = 14/70 and 6 × 10/7 × 10 = 60/70

Step 3

Add the Numerators

Now add the numerators (14 + 60 = 74) and keep the common denominator 70 unchanged.

14 + 60/70 = 74/70

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 74 and 70, which is 2. Divide both the numerator and denominator by 2.

74 ÷ 2/70 ÷ 2 = 37/35

Step 5

Convert Improper Fraction to a Mixed Number

Since the numerator (37) is greater than the denominator (35), divide 37 by 35: it goes in 1 whole time(s) with a remainder of 2, giving the mixed number 1 2/35.

37/35 = 12/35

Step 6

Decimal & Percentage Representation

Dividing the numerator 37 by denominator 35 produces a repeating decimal (approximately 1.057143, or 105.7143%).

37 ÷ 35 = 1.057143 (105.7143%)
