Q. Which of the following options have the same value as 70% 70 \% of 8080 ?\newlineChoose 33 answers:\newlineA 7010080 \frac{70}{100} \cdot 80 \newlineB 0.70.8 0.7 \cdot 0.8 \newlinec 0.780 0.7 \cdot 80 \newlineD 7080 70 \cdot 80 \newlineE 71080 \frac{7}{10} \cdot 80
  1. Convert to Decimal: To find 70%70\% of 8080, we need to convert the percentage to a decimal and multiply it by 8080. 70%70\% as a decimal is 0.70.7, so we calculate 0.7×800.7 \times 80. Calculation: 0.7×80=560.7 \times 80 = 56
  2. Evaluate Option A: Now let's evaluate each option to see which ones are equivalent to 70%70\% of 8080.\newlineOption A: (70100)×80(\frac{70}{100}) \times 80\newlineThis is the same as 0.7×800.7 \times 80 because 70100\frac{70}{100} is 0.70.7.\newlineCalculation: (70100)×80=0.7×80=56(\frac{70}{100}) \times 80 = 0.7 \times 80 = 56
  3. Evaluate Option B: Option B: 0.7×0.80.7 \times 0.8\newlineThis is not the same as 0.7×800.7 \times 80 because 0.80.8 is not equivalent to 8080.\newlineCalculation: 0.7×0.8=0.560.7 \times 0.8 = 0.56
  4. Evaluate Option C: Option C: 0.7×800.7 \times 80\newlineThis is the same as 70%70\% of 8080 because it is the direct calculation of the percentage.\newlineCalculation: 0.7×80=560.7 \times 80 = 56
  5. Evaluate Option D: Option D: 70×8070 \times 80\newlineThis is not the same as 70%70\% of 8080 because it is not taking 70%70\% but rather multiplying 7070 by 8080.\newlineCalculation: 70×80=560070 \times 80 = 5600
  6. Evaluate Option E: Option E: (710)×80(\frac{7}{10}) \times 80\newlineThis is the same as 0.7×800.7 \times 80 because 710\frac{7}{10} is 0.70.7.\newlineCalculation: (710)×80=0.7×80=56(\frac{7}{10}) \times 80 = 0.7 \times 80 = 56
