Exact Answer

==================================================
Problem: What is 2/62 plus 4/21?
Formula / Expression: 2/62 + 4/21
Final Answer: 145/651
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 62 and 21 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 62 × 21 = 1302.
Working: LCD(62, 21) = 1302

Step 2: Convert to Equivalent Fractions with Common Denominator 1302
Multiply the numerator and denominator of 2/62 by 21, and multiply the numerator and denominator of 4/21 by 62 so both fractions share the common base 1302.
Working: 2 × 21/62 × 21 = 42/1302 and 4 × 62/21 × 62 = 248/1302

Step 3: Add the Numerators
Now add the numerators (42 + 248 = 290) and keep the common denominator 1302 unchanged.
Working: 42 + 248/1302 = 290/1302

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 290 and 1302, which is 2. Divide both the numerator and denominator by 2.
Working: 290 ÷ 2/1302 ÷ 2 = 145/651

Step 5: Decimal & Percentage Representation
Dividing the numerator 145 by denominator 651 produces a repeating decimal (approximately 0.222734, or 22.2734%).
Working: 145 ÷ 651 = 0.222734 (22.2734%)

Key Values:
- Simplified Fraction: 145/651
- Mixed Number Form: 145/651
- Decimal Value: 0.222734
- Percentage: 22.2734%

Step-by-Step Solution: 2/62 + 4/21

Step 1

Find the Least Common Denominator (LCD)

The denominators 62 and 21 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 62 × 21 = 1302.

LCD(62, 21) = 1302

Step 2

Convert to Equivalent Fractions with Common Denominator 1302

Multiply the numerator and denominator of 2/62 by 21, and multiply the numerator and denominator of 4/21 by 62 so both fractions share the common base 1302.

2 × 21/62 × 21 = 42/1302 and 4 × 62/21 × 62 = 248/1302

Step 3

Add the Numerators

Now add the numerators (42 + 248 = 290) and keep the common denominator 1302 unchanged.

42 + 248/1302 = 290/1302

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 290 and 1302, which is 2. Divide both the numerator and denominator by 2.

290 ÷ 2/1302 ÷ 2 = 145/651

Step 5

Decimal & Percentage Representation

Dividing the numerator 145 by denominator 651 produces a repeating decimal (approximately 0.222734, or 22.2734%).

145 ÷ 651 = 0.222734 (22.2734%)
