Exact Answer

==================================================
Problem: What is 11/46 plus 7/13?
Formula / Expression: 11/46 + 7/13
Final Answer: 465/598
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 46 and 13 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 46 × 13 = 598.
Working: LCD(46, 13) = 598

Step 2: Convert to Equivalent Fractions with Common Denominator 598
Multiply the numerator and denominator of 11/46 by 13, and multiply the numerator and denominator of 7/13 by 46 so both fractions share the common base 598.
Working: 11 × 13/46 × 13 = 143/598 and 7 × 46/13 × 46 = 322/598

Step 3: Add the Numerators
Now add the numerators (143 + 322 = 465) and keep the common denominator 598 unchanged.
Working: 143 + 322/598 = 465/598

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 465 and 598 is 1, confirming that 465/598 cannot be reduced further—it is already in its simplest irreducible form.
Working: 465/598

Step 5: Decimal & Percentage Representation
Dividing the numerator 465 by denominator 598 produces a repeating decimal (approximately 0.777592, or 77.7592%).
Working: 465 ÷ 598 = 0.777592 (77.7592%)

Step-by-Step Solution: 11/46 + 7/13

Step 1

Find the Least Common Denominator (LCD)

The denominators 46 and 13 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 46 × 13 = 598.

LCD(46, 13) = 598

Step 2

Convert to Equivalent Fractions with Common Denominator 598

Multiply the numerator and denominator of 11/46 by 13, and multiply the numerator and denominator of 7/13 by 46 so both fractions share the common base 598.

11 × 13/46 × 13 = 143/598 and 7 × 46/13 × 46 = 322/598

Step 3

Add the Numerators

Now add the numerators (143 + 322 = 465) and keep the common denominator 598 unchanged.

143 + 322/598 = 465/598

Step 4

Check if the Fraction Can Be Simplified
