there are 20 students in mark`s homeroom class. Ten percent of the students in marks homeroom class are also in art class He finds the number of students in his homeroom class who are also in art class like this . Can you tell me the answer of how many error he made.
To find the number of students in Mark's homeroom class who are also in the art class, you need to calculate 10% of the total number of students in Mark's homeroom class.
Step 1: Calculate 10% of 20
To find 10% of a number, you can multiply the number by 0.1.
10% of 20 = 20 * 0.1 = 2
So, there are 2 students in Mark's homeroom class who are also in the art class.
Now, to address the error Mark made, we need to know what information was provided about the error. If the error is related to the calculation itself, it could be that Mark made a mistake in the multiplication (e.g., multiplying by 0.01 instead of 0.1). If the error is about the interpretation of the problem, we would need additional information to identify the error.
Please provide more details about the specific error so we can assist you better.
It would help if you proofread your questions before you posted them.
