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

Exact Answer

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

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
Notice that 10 is an exact multiple of 2 (2 × 5 = 10). The Least Common Denominator (LCD) is simply 10, meaning we only need to scale one fraction.
Working: LCD(2, 10) = 10

Step 2: Convert to Equivalent Fractions with Common Denominator 10
Multiply the numerator and denominator of 1/2 by 5, and multiply the numerator and denominator of 5/10 by 1 so both fractions share the common base 10.
Working: 1 × 5/2 × 5 = 5/10 and 5 × 1/10 × 1 = 5/10

Step 3: Add the Numerators
Now add the numerators (5 + 5 = 10) and keep the common denominator 10 unchanged.
Working: 5 + 5/10 = 10/10

Step 4: Simplify to an Exact Whole Number
Notice that the numerator (10) is completely divisible by the denominator (10). Dividing 10 by 10 yields the whole number 1 with zero remainder.
Working: 10/10 = 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%)

LCD(2, 10) = 10

Step 2

Convert to Equivalent Fractions with Common Denominator 10

Multiply the numerator and denominator of 1/2 by 5, and multiply the numerator and denominator of 5/10 by 1 so both fractions share the common base 10.

1 × 5/2 × 5 = 5/10 and 5 × 1/10 × 1 = 5/10

Step 3

Add the Numerators

Now add the numerators (5 + 5 = 10) and keep the common denominator 10 unchanged.

5 + 5/10 = 10/10
