What is 2/25 plus 4/8? (Answer: 29/50)

Exact Answer

==================================================
Problem: What is 2/25 plus 4/8?
Formula / Expression: 2/25 + 4/8
Final Answer: 29/50
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 25 and 8 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 25 × 8 = 200.
Working: LCD(25, 8) = 200

Step 2: Convert to Equivalent Fractions with Common Denominator 200
Multiply the numerator and denominator of 2/25 by 8, and multiply the numerator and denominator of 4/8 by 25 so both fractions share the common base 200.
Working: 2 × 8/25 × 8 = 16/200 and 4 × 25/8 × 25 = 100/200

Step 3: Add the Numerators
Now add the numerators (16 + 100 = 116) and keep the common denominator 200 unchanged.
Working: 16 + 100/200 = 116/200

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 116 and 200, which is 4. Divide both the numerator and denominator by 4.
Working: 116 ÷ 4/200 ÷ 4 = 29/50

Step 5: Decimal & Percentage Representation
Dividing the numerator 29 by denominator 50 yields an exact terminating decimal of 0.58 (or 58%).
Working: 29 ÷ 50 = 0.58 (58%)

Key Values:
- Simplified Fraction: 29/50
- Mixed Number Form: 29/50
- Decimal Value: 0.58

The denominators 25 and 8 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 25 × 8 = 200.

LCD(25, 8) = 200

Step 2

Convert to Equivalent Fractions with Common Denominator 200

Multiply the numerator and denominator of 2/25 by 8, and multiply the numerator and denominator of 4/8 by 25 so both fractions share the common base 200.

2 × 8/25 × 8 = 16/200 and 4 × 25/8 × 25 = 100/200

Step 3

Add the Numerators

Now add the numerators (16 + 100 = 116) and keep the common denominator 200 unchanged.

16 + 100/200 = 116/200

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 116 and 200, which is 4. Divide both the numerator and denominator by 4.

116 ÷ 4/200 ÷ 4 = 29/50

Step 5
