Difficulty: Easy
Correct Answer: 15 / 11
Explanation:
Introduction / Context:
This problem demonstrates strict adherence to operator precedence (division before addition) inside both numerator and denominator. Mastery of BODMAS/PEMDAS prevents common mistakes.
Given Data / Assumptions:
Concept / Approach:
Resolve the division terms first in both numerator and denominator. Then perform the additions, and finally divide the simplified numerator by the simplified denominator.
Step-by-Step Solution:
Numerator: 7 + 7 + (7 ÷ 7) = 7 + 7 + 1 = 15.Denominator: 5 + 5 + (5 ÷ 5) = 5 + 5 + 1 = 11.Overall value = 15 / 11.
Verification / Alternative check:
Convert to mixed numbers if desired: 15/11 = 1 and 4/11, but the fractional form is exact and preferred.
Why Other Options Are Wrong:
1 would require numerator = denominator; 1/5 and 3/11 result from misplacing the division; 11/15 is the reciprocal, not the value.
Common Pitfalls:
Adding before dividing; treating 7 ÷ 7 as 7; forgetting to compute the 5 ÷ 5 term in the denominator.
Final Answer:
15 / 11
