Step-by-step explanation:

The formula you can use to find the percentage of change is:

Where is the final amount and is the initial amount and %C is the percentage of change.

In this problem we know that the initial length of the table is:

Then

The final length is:

Then

Note that there was a reduction in length, therefore the change will be negative.

Finally the percent of change in length is -18.75%

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
