To find 275% of 4, you would take the following steps:

  1. Find the decimal equivalent of 275%, or 2.75.

    • This is the correct first step because it converts the percentage into a decimal form, which is needed for multiplication.

  2. Multiply 2.75 by 4 to get 11 books.

    • This step correctly applies the decimal to the number of books read, yielding the answer you are looking for.

The other options can be analyzed as follows:

  • Find the decimal equivalent of 4%, or 0.4.

    • This step is not necessary for calculating 275% of 4, as we do not need to convert 4% for this particular problem.

  • Multiply 0.4 by 275 to get 110 books.

    • This step is not relevant to finding 275% of 4, as it involves an incorrect use of percentages and does not provide a valid answer.

  • Estimate to check your answer by finding 300% of 4.

    • While this is a potential way to check your work by providing a rough estimate (300% of 4 would be 12), it isn't necessary as a step in calculating 275% directly.

In conclusion, the correct steps to take from the provided options are:

  • Find the decimal equivalent of 275%, or 2.75.
  • Multiply 2.75 by 4 to get 11 books.
