What is 3/6 plus 3/5? (Answer: 11/10)

Exact Answer

==================================================
Problem: What is 3/6 plus 3/5?
Formula / Expression: 3/6 + 3/5
Final Answer: 1 1/10 (11/10)
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 6 and 5 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 6 × 5 = 30.
Working: LCD(6, 5) = 30

Step 2: Convert to Equivalent Fractions with Common Denominator 30
Multiply the numerator and denominator of 3/6 by 5, and multiply the numerator and denominator of 3/5 by 6 so both fractions share the common base 30.
Working: 3 × 5/6 × 5 = 15/30 and 3 × 6/5 × 6 = 18/30

Step 3: Add the Numerators
Now add the numerators (15 + 18 = 33) and keep the common denominator 30 unchanged.
Working: 15 + 18/30 = 33/30

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 33 and 30, which is 3. Divide both the numerator and denominator by 3.
Working: 33 ÷ 3/30 ÷ 3 = 11/10

Step 5: Convert Improper Fraction to a Mixed Number
Since the numerator (11) is greater than the denominator (10), divide 11 by 10: it goes in 1 whole time(s) with a remainder of 1, giving the mixed number 1 1/10.
Working: 11/10 = 1 1/10

Step 6: Decimal & Percentage Representation
Dividing the numerator 11 by denominator 10 yields an exact terminating decimal of 1.1 (or 110%).
Working: 11 ÷ 10 = 1.1 (110%)

Key Values:
- Simplified Fraction: 11/10
- Mixed Number Form: 1 1/10
- Decimal Value: 1.1
- Percentage: 110%

Step-by-Step Solution: 3/6 + 3/5

Step 1

Find the Least Common Denominator (LCD)

The denominators 6 and 5 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 6 × 5 = 30.

LCD(6, 5) = 30

Step 2

Convert to Equivalent Fractions with Common Denominator 30

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

3 × 5/6 × 5 = 15/30 and 3 × 6/5 × 6 = 18/30

Step 3

Add the Numerators

Now add the numerators (15 + 18 = 33) and keep the common denominator 30 unchanged.

15 + 18/30 = 33/30

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 33 and 30, which is 3. Divide both the numerator and denominator by 3.

33 ÷ 3/30 ÷ 3 = 11/10

Step 5

Convert Improper Fraction to a Mixed Number

Since the numerator (11) is greater than the denominator (10), divide 11 by 10: it goes in 1 whole time(s) with a remainder of 1, giving the mixed number 1 1/10.

11/10 = 11/10

Step 6

Decimal & Percentage Representation

Dividing the numerator 11 by denominator 10 yields an exact terminating decimal of 1.1 (or 110%).

11 ÷ 10 = 1.1 (110%)
