Question

A piece of rectangular metal has 8 holes punched in it that lie in a straight line.If there are 1 1/16 inches between the centers of two consecutive holes find the distance from the center of the first hole to the center of the last hole. _______ inches (Mixed number answer)

Answer 1

Since you start at the first hole, you only want the distance between that and the eighth hole.

7 * 1 1/16 = ?

I hope this helps. Thanks for asking.

Answer 2

Multiply 7 times the given number of inches.

I will first convert 1_1/16 to an improper fraction.

So, 1_1/16 becomes 17/16.

We can multiply 7 times 17/16 a lot easier.

Then:

7 x 17/16 = 7_7/16 is the distance.

Done!
