Q. Which is the most accurate way to estimate 76%76\% of 9090?\newlineChoices:\newline(A) 23×93\frac{2}{3} \times 93\newline(B) 34×93\frac{3}{4} \times 93\newline(C) 34×92\frac{3}{4} \times 92\newline(D) 23×92\frac{2}{3} \times 92
  1. Calculate 7676% of 9090: Calculate 76%76\% of 9090 directly for comparison.\newlineCalculation: 0.76×90=68.40.76 \times 90 = 68.4
  2. Estimate using choice (A): Estimate using choice (A): 23×93\frac{2}{3} \times 93.\newlineCalculation: (23)×93=62\left(\frac{2}{3}\right) \times 93 = 62
  3. Estimate using choice (B): Estimate using choice (B): 34×93\frac{3}{4} \times 93.\newlineCalculation: (34)×93=69.75(\frac{3}{4}) \times 93 = 69.75
  4. Estimate using choice (C): Estimate using choice (C): 34×92\frac{3}{4} \times 92.\newlineCalculation: (34)×92=69\left(\frac{3}{4}\right) \times 92 = 69
  5. Estimate using choice (D): Estimate using choice (D): 23×92\frac{2}{3} \times 92.\newlineCalculation: (23)×92=61.33\left(\frac{2}{3}\right) \times 92 = 61.33
