What is 2/25 plus 4/5? (Answer: 22/25)

Exact Answer

==================================================
Problem: What is 2/25 plus 4/5?
Formula / Expression: 2/25 + 4/5
Final Answer: 22/25
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
Notice that 25 is an exact multiple of 5 (5 × 5 = 25). The Least Common Denominator (LCD) is simply 25, meaning we only need to scale one fraction.
Working: LCD(25, 5) = 25

Step 2: Convert to Equivalent Fractions with Common Denominator 25
Multiply the numerator and denominator of 2/25 by 1, and multiply the numerator and denominator of 4/5 by 5 so both fractions share the common base 25.
Working: 2 × 1/25 × 1 = 2/25 and 4 × 5/5 × 5 = 20/25

Step 3: Add the Numerators
Now add the numerators (2 + 20 = 22) and keep the common denominator 25 unchanged.
Working: 2 + 20/25 = 22/25

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 22 and 25 is 1, confirming that 22/25 cannot be reduced further—it is already in its simplest irreducible form.
Working: 22/25

Step 5: Decimal & Percentage Representation
Dividing the numerator 22 by denominator 25 yields an exact terminating decimal of 0.88 (or 88%).
Working: 22 ÷ 25 = 0.88 (88%)

Key Values:
- Simplified Fraction: 22/25
- Mixed Number Form: 22/25
