What is 8/22 plus 10/13? (Answer: 162/143)

Exact Answer

==================================================
Problem: What is 8/22 plus 10/13?
Formula / Expression: 8/22 + 10/13
Final Answer: 1 19/143 (162/143)
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 22 and 13 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 22 × 13 = 286.
Working: LCD(22, 13) = 286

Step 2: Convert to Equivalent Fractions with Common Denominator 286
Multiply the numerator and denominator of 8/22 by 13, and multiply the numerator and denominator of 10/13 by 22 so both fractions share the common base 286.
Working: 8 × 13/22 × 13 = 104/286 and 10 × 22/13 × 22 = 220/286

Step 3: Add the Numerators
Now add the numerators (104 + 220 = 324) and keep the common denominator 286 unchanged.
Working: 104 + 220/286 = 324/286

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 324 and 286, which is 2. Divide both the numerator and denominator by 2.
Working: 324 ÷ 2/286 ÷ 2 = 162/143

Step 5: Convert Improper Fraction to a Mixed Number
Since the numerator (162) is greater than the denominator (143), divide 162 by 143: it goes in 1 whole time(s) with a remainder of 19, giving the mixed number 1 19/143.
Working: 162/143 = 1 19/143

Step 6: Decimal & Percentage Representation
Dividing the numerator 162 by denominator 143 produces a repeating decimal (approximately 1.132867, or 113.2867%).
Working: 162 ÷ 143 = 1.132867 (113.2867%)

Key Values:
- Simplified Fraction: 162/143
- Mixed Number Form: 1 19/143
- Decimal Value: 1.132867
- Percentage: 113.2867%

Step-by-Step Solution: 8/22 + 10/13

Step 1

Find the Least Common Denominator (LCD)

The denominators 22 and 13 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 22 × 13 = 286.

LCD(22, 13) = 286

Step 2

Convert to Equivalent Fractions with Common Denominator 286

Multiply the numerator and denominator of 8/22 by 13, and multiply the numerator and denominator of 10/13 by 22 so both fractions share the common base 286.

8 × 13/22 × 13 = 104/286 and 10 × 22/13 × 22 = 220/286

Step 3

Add the Numerators

Now add the numerators (104 + 220 = 324) and keep the common denominator 286 unchanged.

104 + 220/286 = 324/286

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 324 and 286, which is 2. Divide both the numerator and denominator by 2.

324 ÷ 2/286 ÷ 2 = 162/143

Step 5

Convert Improper Fraction to a Mixed Number

Since the numerator (162) is greater than the denominator (143), divide 162 by 143: it goes in 1 whole time(s) with a remainder of 19, giving the mixed number 1 19/143.

162/143 = 119/143

Step 6

Decimal & Percentage Representation

Dividing the numerator 162 by denominator 143 produces a repeating decimal (approximately 1.132867, or 113.2867%).

162 ÷ 143 = 1.132867 (113.2867%)
