Exact Answer

==================================================
Problem: What is 14/50 plus 8/21?
Formula / Expression: 14/50 + 8/21
Final Answer: 347/525
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 50 and 21 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 50 × 21 = 1050.
Working: LCD(50, 21) = 1050

Step 2: Convert to Equivalent Fractions with Common Denominator 1050
Multiply the numerator and denominator of 14/50 by 21, and multiply the numerator and denominator of 8/21 by 50 so both fractions share the common base 1050.
Working: 14 × 21/50 × 21 = 294/1050 and 8 × 50/21 × 50 = 400/1050

Step 3: Add the Numerators
Now add the numerators (294 + 400 = 694) and keep the common denominator 1050 unchanged.
Working: 294 + 400/1050 = 694/1050

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 694 and 1050, which is 2. Divide both the numerator and denominator by 2.
Working: 694 ÷ 2/1050 ÷ 2 = 347/525

Step 5: Decimal & Percentage Representation
Dividing the numerator 347 by denominator 525 produces a repeating decimal (approximately 0.660952, or 66.0952%).
Working: 347 ÷ 525 = 0.660952 (66.0952%)

Key Values:
- Simplified Fraction: 347/525
- Mixed Number Form: 347/525
- Decimal Value: 0.660952
- Percentage: 66.0952%

Step-by-Step Solution: 14/50 + 8/21

Step 1

Find the Least Common Denominator (LCD)

The denominators 50 and 21 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 50 × 21 = 1050.

LCD(50, 21) = 1050

Step 2

Convert to Equivalent Fractions with Common Denominator 1050

Multiply the numerator and denominator of 14/50 by 21, and multiply the numerator and denominator of 8/21 by 50 so both fractions share the common base 1050.

14 × 21/50 × 21 = 294/1050 and 8 × 50/21 × 50 = 400/1050

Step 3

Add the Numerators

Now add the numerators (294 + 400 = 694) and keep the common denominator 1050 unchanged.

294 + 400/1050 = 694/1050

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 694 and 1050, which is 2. Divide both the numerator and denominator by 2.

694 ÷ 2/1050 ÷ 2 = 347/525

Step 5

Decimal & Percentage Representation

Dividing the numerator 347 by denominator 525 produces a repeating decimal (approximately 0.660952, or 66.0952%).

347 ÷ 525 = 0.660952 (66.0952%)
