What is 7/11 plus 2/3? (Answer: 43/33)

Exact Answer

==================================================
Problem: What is 7/11 plus 2/3?
Formula / Expression: 7/11 + 2/3
Final Answer: 1 10/33 (43/33)
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 11 and 3 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 11 × 3 = 33.
Working: LCD(11, 3) = 33

Step 2: Convert to Equivalent Fractions with Common Denominator 33
Multiply the numerator and denominator of 7/11 by 3, and multiply the numerator and denominator of 2/3 by 11 so both fractions share the common base 33.
Working: 7 × 3/11 × 3 = 21/33 and 2 × 11/3 × 11 = 22/33

Step 3: Add the Numerators
Now add the numerators (21 + 22 = 43) and keep the common denominator 33 unchanged.
Working: 21 + 22/33 = 43/33

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 43 and 33 is 1, confirming that 43/33 cannot be reduced further—it is already in its simplest irreducible form.
Working: 43/33

Step 5: Convert Improper Fraction to a Mixed Number
Since the numerator (43) is greater than the denominator (33), divide 43 by 33: it goes in 1 whole time(s) with a remainder of 10, giving the mixed number 1 10/33.
Working: 43/33 = 1 10/33

Step 6: Decimal & Percentage Representation
Dividing the numerator 43 by denominator 33 produces a repeating decimal (approximately 1.30303, or 130.303%).
Working: 43 ÷ 33 = 1.30303 (130.303%)

Key Values:
- Simplified Fraction: 43/33
- Mixed Number Form: 1 10/33
- Decimal Value: 1.30303
- Percentage: 130.303%

Step-by-Step Solution: 7/11 + 2/3

Step 1

Find the Least Common Denominator (LCD)

The denominators 11 and 3 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 11 × 3 = 33.

LCD(11, 3) = 33

Step 2

Convert to Equivalent Fractions with Common Denominator 33

Multiply the numerator and denominator of 7/11 by 3, and multiply the numerator and denominator of 2/3 by 11 so both fractions share the common base 33.

7 × 3/11 × 3 = 21/33 and 2 × 11/3 × 11 = 22/33

Step 3

Add the Numerators

Now add the numerators (21 + 22 = 43) and keep the common denominator 33 unchanged.

21 + 22/33 = 43/33

Step 4

Check if the Fraction Can Be Simplified

The Greatest Common Divisor (GCD) of 43 and 33 is 1, confirming that 43/33 cannot be reduced further—it is already in its simplest irreducible form.

43/33

Step 5

Convert Improper Fraction to a Mixed Number

Since the numerator (43) is greater than the denominator (33), divide 43 by 33: it goes in 1 whole time(s) with a remainder of 10, giving the mixed number 1 10/33.

43/33 = 110/33

Step 6

Decimal & Percentage Representation

Dividing the numerator 43 by denominator 33 produces a repeating decimal (approximately 1.30303, or 130.303%).

43 ÷ 33 = 1.30303 (130.303%)
