What is 5/25 plus 2/4? (Answer: 7/10)

Exact Answer

==================================================
Problem: What is 5/25 plus 2/4?
Formula / Expression: 5/25 + 2/4
Final Answer: 7/10
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 25 and 4 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 25 × 4 = 100.
Working: LCD(25, 4) = 100

Step 2: Convert to Equivalent Fractions with Common Denominator 100
Multiply the numerator and denominator of 5/25 by 4, and multiply the numerator and denominator of 2/4 by 25 so both fractions share the common base 100.
Working: 5 × 4/25 × 4 = 20/100 and 2 × 25/4 × 25 = 50/100

Step 3: Add the Numerators
Now add the numerators (20 + 50 = 70) and keep the common denominator 100 unchanged.
Working: 20 + 50/100 = 70/100

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 70 and 100, which is 10. Divide both the numerator and denominator by 10.
Working: 70 ÷ 10/100 ÷ 10 = 7/10

Step 5: Decimal & Percentage Representation
Dividing the numerator 7 by denominator 10 yields an exact terminating decimal of 0.7 (or 70%).
Working: 7 ÷ 10 = 0.7 (70%)

Key Values:
- Simplified Fraction: 7/10
- Mixed Number Form: 7/10
- Decimal Value: 0.7
- Percentage: 70%

The denominators 25 and 4 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 25 × 4 = 100.

LCD(25, 4) = 100

Step 2

Convert to Equivalent Fractions with Common Denominator 100

Multiply the numerator and denominator of 5/25 by 4, and multiply the numerator and denominator of 2/4 by 25 so both fractions share the common base 100.

5 × 4/25 × 4 = 20/100 and 2 × 25/4 × 25 = 50/100

Step 3

Add the Numerators

Now add the numerators (20 + 50 = 70) and keep the common denominator 100 unchanged.

20 + 50/100 = 70/100

Step 4
