Michelle is building shelves for her room. she has a plank 137 inches long that she wants to cut into 7 shelves of equal length. the plank has jagged ends, so she will start by cutting 2 inches off each end. how long will each shelf be?

19 inches.

Step-by-step explanation:

We have been given that Michelle has a plank 137 inches long that she wants to cut into 7 shelves of equal length. The plank has jagged ends, so she will start by cutting 2 inches off each end.

Since she cute 2 inches from each end, so she will cut 2*2 inches or 4 inches from both ends.

The length of plank left after cutting off jagged ends would be .

Now, we will divide 133 by 7 to find length of each shelf.

Therefore, the length of each shelf would be 19 inches.

0.6, 3/5, and 6% are the 3 same portion.

but, when they're all changed to a decimal they would equal to 0.6.

hope this , good luck!
