21. Simplify the expression above. Which of the following is the correct answer? 2^5/8 + 1/3
Answer: C
8/7
The expression 2^5/8 + 1/3 simplifies to 8/7, which is the correct answer. This result is derived from calculating each term and finding a common denominator.
A) 1/7
Option A is incorrect because simplifying the expression does not yield 1/7. The calculation shows that both terms contribute to a larger fraction, specifically leading towards a value greater than one.
B) 8/19
Option B is also incorrect. The sum of the fractions does not equal 8/19 when calculated properly. The components, 2^5/8 and 1/3, combine to form a fraction that simplifies significantly differently.
C) 8/7
This is the correct option. The expression 2^5/8 equals 1 and 1/3 equals 1/3, which when added together results in 8/7 after finding a common denominator and simplifying.
D) 7 1/8
Option D is incorrect as it represents a mixed number that does not correspond to the result of the given arithmetic. The actual simplification does not approach a whole number plus a fraction of 1/8.
Conclusion
The correct answer, 8/7, accurately reflects the result of the simplified expression. All other options either miscalculate the total or misinterpret the fractions involved, confirming that they are not valid answers in this context.
