The boys at academy camp are working on math problems to prepare for a math competition. the camp leader has put a problem on the board for the students to work on. paolo does the following problem incorrectly. explain the error and redo the problem showing the correct answerpaolo's answer -0.43-0.2 = -0.23 

We don't actually know what the problem originally was, so we don't know what the error was or what the correct answer should be.

If the numbers on the left are given, and the problem is to find the number on the right, then ...

Paolo added 0.2 instead of subtracting it.

-0.43 -0.2 = -0.63 . . . . . correct answer

If the left and right numbers are given and the problem is to find the one in the middle, then ...

Paolo incorrectly calculated 0.43 -0.23, getting -0.2 instead of +0.2.

-0.43 +0.2 = -0.23 . . . . correct answer

If the problem is to find the term on the left, then ...

Paolo incorrectly added 0.2 and -0.23, getting -0.43 instead of -0.03.

-0.03 -0.2 = -0.23 . . . . correct answer

answer: the answer is one of

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following
