Exact Answer

==================================================
Problem: What is 9/49 plus 3/15?
Formula / Expression: 9/49 + 3/15
Final Answer: 94/245
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 49 and 15 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 49 × 15 = 735.
Working: LCD(49, 15) = 735

Step 2: Convert to Equivalent Fractions with Common Denominator 735
Multiply the numerator and denominator of 9/49 by 15, and multiply the numerator and denominator of 3/15 by 49 so both fractions share the common base 735.
Working: 9 × 15/49 × 15 = 135/735 and 3 × 49/15 × 49 = 147/735

Step 3: Add the Numerators
Now add the numerators (135 + 147 = 282) and keep the common denominator 735 unchanged.
Working: 135 + 147/735 = 282/735

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 282 and 735, which is 3. Divide both the numerator and denominator by 3.
Working: 282 ÷ 3/735 ÷ 3 = 94/245

Step 5: Decimal & Percentage Representation
Dividing the numerator 94 by denominator 245 produces a repeating decimal (approximately 0.383673, or 38.3673%).
Working: 94 ÷ 245 = 0.383673 (38.3673%)

Key Values:
- Simplified Fraction: 94/245
- Mixed Number Form: 94/245
- Decimal Value: 0.383673

Step-by-Step Solution: 9/49 + 3/15

Step 1

Find the Least Common Denominator (LCD)

The denominators 49 and 15 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 49 × 15 = 735.

LCD(49, 15) = 735

Step 2

Convert to Equivalent Fractions with Common Denominator 735

Multiply the numerator and denominator of 9/49 by 15, and multiply the numerator and denominator of 3/15 by 49 so both fractions share the common base 735.

9 × 15/49 × 15 = 135/735 and 3 × 49/15 × 49 = 147/735

Step 3

Add the Numerators

Now add the numerators (135 + 147 = 282) and keep the common denominator 735 unchanged.

135 + 147/735 = 282/735

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 282 and 735, which is 3. Divide both the numerator and denominator by 3.

282 ÷ 3/735 ÷ 3 = 94/245

Step 5

Decimal & Percentage Representation

Dividing the numerator 94 by denominator 245 produces a repeating decimal (approximately 0.383673, or 38.3673%).

94 ÷ 245 = 0.383673 (38.3673%)
