Question

A piece of sheet metal is 28 1/2 inches wide. A piece 13 5/16 inches is cut off. How wide will the

remaining piece of sheet metal be?

Answer 1

To find the width of the remaining piece of sheet metal, we need to subtract the width of the piece that was cut off from the original width.

First, we need to convert the mixed numbers to improper fractions:

28 1/2 = 57/2

13 5/16 = (13 x 16 + 5)/16 = 213/16

Now we can subtract:

57/2 - 213/16

To subtract these fractions, we need to find a common denominator:

57/2 = 464/16

464/16 - 213/16 = 251/16

So the width of the remaining piece of sheet metal is 251/16 inches.

We can also convert this back to a mixed number:

251/16 = 15 11/16

Therefore, the remaining piece of sheet metal is 15 11/16 inches wide.
