Exact Answer

==================================================
Problem: What is 2/7 plus 5/7?
Formula / Expression: 2/7 + 5/7
Final Answer: 1
==================================================

Step-by-Step Solution:

Step 1: Check the Denominators (Like Fractions)
Both fractions already share the identical denominator (7). Because these are like fractions, no conversion to a common denominator is required—we directly add their numerators while keeping the denominator 7.
Working: 2/7 + 5/7

Step 2: Add the Numerators
Now add the numerators (2 + 5 = 7) and keep the common denominator 7 unchanged.
Working: 2 + 5/7 = 7/7

Step 3: Simplify to an Exact Whole Number
Notice that the numerator (7) is completely divisible by the denominator (7). Dividing 7 by 7 yields the whole number 1 with zero remainder.
Working: 7/7 = 1

Step 4: Decimal & Percentage Representation
Dividing the numerator 1 by denominator 1 yields an exact terminating decimal of 1 (or 100%).
Working: 1 ÷ 1 = 1 (100%)
