What is 2/4 plus 5/10? (Answer: 1)

Exact Answer

==================================================
Problem: What is 2/4 plus 5/10?
Formula / Expression: 2/4 + 5/10
Final Answer: 1
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 4 and 10 share a common factor (GCD = 2). Finding their Least Common Multiple gives an LCD of 20 (which is smaller than their product 4 × 10 = 40, keeping the calculation simpler).
Working: LCD(4, 10) = 20

Step 2: Convert to Equivalent Fractions with Common Denominator 20
Multiply the numerator and denominator of 2/4 by 5, and multiply the numerator and denominator of 5/10 by 2 so both fractions share the common base 20.
Working: 2 × 5/4 × 5 = 10/20 and 5 × 2/10 × 2 = 10/20

Step 3: Add the Numerators
Now add the numerators (10 + 10 = 20) and keep the common denominator 20 unchanged.
Working: 10 + 10/20 = 20/20

Step 4: Simplify to an Exact Whole Number
Notice that the numerator (20) is completely divisible by the denominator (20). Dividing 20 by 20 yields the whole number 1 with zero remainder.
Working: 20/20 = 1

Step 5: Decimal & Percentage Representation
Dividing the numerator 1 by denominator 1 yields an exact terminating decimal of 1 (or 100%).
Working: 1 ÷ 1 = 1 (100%)
