Q. The number 2222 is increased to 3939 . What is the percentage by which the number was increased, to the nearest tenth of a percent?\newlineAnswer:
  1. Determine Increase Amount: Determine the amount of increase from the original number.\newlineTo find the increase, subtract the original number from the new number.\newlineIncrease =New number−Original number= \text{New number} - \text{Original number}\newlineIncrease =39−22= 39 - 22\newlineIncrease =17= 17
  2. Calculate Percentage Increase: Calculate the percentage increase based on the original number.\newlineTo find the percentage increase, divide the increase by the original number and then multiply by 100100 to convert it to a percentage.\newlinePercentage increase = (Increase÷Original number)×100(\text{Increase} \div \text{Original number}) \times 100\newlinePercentage increase = (17÷22)×100(17 \div 22) \times 100
  3. Perform Division and Multiplication: Perform the division and multiplication to find the percentage increase.\newlinePercentage increase = (17÷22)×100(17 \div 22) \times 100\newlinePercentage increase ≈0.7727×100\approx 0.7727 \times 100\newlinePercentage increase ≈77.27\approx 77.27
  4. Round Percentage Increase: Round the percentage increase to the nearest tenth of a percent.\newlineRounded percentage increase ≈77.3%\approx 77.3\%
