What is 4/25 plus 2/8? (Answer: 41/100)

Exact Answer

==================================================
Problem: What is 4/25 plus 2/8?
Formula / Expression: 4/25 + 2/8
Final Answer: 41/100
==================================================

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 4/25 by 8, and multiply the numerator and denominator of 2/8 by 25 so both fractions share the common base 200.
Working: 4 × 8/25 × 8 = 32/200 and 2 × 25/8 × 25 = 50/200

Step 3: Add the Numerators
Now add the numerators (32 + 50 = 82) and keep the common denominator 200 unchanged.
Working: 32 + 50/200 = 82/200

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 82 and 200, which is 2. Divide both the numerator and denominator by 2.
Working: 82 ÷ 2/200 ÷ 2 = 41/100

Step 5: Decimal & Percentage Representation
Dividing the numerator 41 by denominator 100 yields an exact terminating decimal of 0.41 (or 41%).
Working: 41 ÷ 100 = 0.41 (41%)

Key Values:
- Simplified Fraction: 41/100
- Mixed Number Form: 41/100
- Decimal Value: 0.41
- Percentage: 41%

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

4 × 8/25 × 8 = 32/200 and 2 × 25/8 × 25 = 50/200

Step 3

Add the Numerators

Now add the numerators (32 + 50 = 82) and keep the common denominator 200 unchanged.

32 + 50/200 = 82/200

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 82 and 200, which is 2. Divide both the numerator and denominator by 2.

82 ÷ 2/200 ÷ 2 = 41/100

Step 5
