What is 3/9 plus 2/3? (Answer: 1)

Exact Answer

==================================================
Problem: What is 3/9 plus 2/3?
Formula / Expression: 3/9 + 2/3
Final Answer: 1
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
Notice that 9 is an exact multiple of 3 (3 × 3 = 9). The Least Common Denominator (LCD) is simply 9, meaning we only need to scale one fraction.
Working: LCD(9, 3) = 9

Step 2: Convert to Equivalent Fractions with Common Denominator 9
Multiply the numerator and denominator of 3/9 by 1, and multiply the numerator and denominator of 2/3 by 3 so both fractions share the common base 9.
Working: 3 × 1/9 × 1 = 3/9 and 2 × 3/3 × 3 = 6/9

Step 3: Add the Numerators
Now add the numerators (3 + 6 = 9) and keep the common denominator 9 unchanged.
Working: 3 + 6/9 = 9/9

Step 4: Simplify to an Exact Whole Number
Notice that the numerator (9) is completely divisible by the denominator (9). Dividing 9 by 9 yields the whole number 1 with zero remainder.
Working: 9/9 = 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%)
