Which is the most accurate way to estimate 50% of 75? Choices: (A)1/3 × 77 (B)1/2 × 76 (C)1/2 × 77 (D)1/3 × 76

Identify Operation: Identify the mathematical operation needed to find 50% of 75. Calculation: 50% of 75 = 0.5 × 75 = 37.5 Calculate 50% of 75: Compare the result with the given choices to find the closest estimate. Calculation: (A) 1/3 × 77 = 25.67 (B) 1/2 × 76 = 38 (C) 1/2 × 77 = 38.5 (D) 1/3 × 76 = 25.33 Compare with Choices: Choice (B) and (C) are closest to 37.5, but (C) is slightly higher. Since we need the most accurate estimate, (B) is the best choice. Calculation: 38 is closer to 37.5 than 38.5

50\%

75

\newline

Choices:

\newline

(A)

\frac{1}{3} \times 77

\newline

(B)

\frac{1}{2} \times 76

\newline

(C)

\frac{1}{2} \times 77

\newline

(D)

\frac{1}{3} \times 76

Identify Operation: Identify the mathematical operation needed to find $50\%$ of $75$ . Calculation: $50\%$ of $75 = 0.5 \times 75 = 37.5$
Calculate $50\%$ of $75$ : Compare the result with the given choices to find the closest estimate. Calculation: $\newline$ (A) $\frac{1}{3} \times 77 = 25.67$ $\newline$ (B) $\frac{1}{2} \times 76 = 38$ $\newline$ (C) $\frac{1}{2} \times 77 = 38.5$ $\newline$ (D) $\frac{1}{3} \times 76 = 25.33$
Compare with Choices: Choice (B) and (C) are closest to $37.5$ , but (C) is slightly higher. Since we need the most accurate estimate, (B) is the best choice. Calculation: $38$ is closer to $37.5$ than $38.5$
