Question

Luke's pencil is 8 inches long. Riley's pencil is only 3 inches long. How many inches longer is Luke's pencil?

Answer 1

Luke's pencil is longer by 5 inches. See Explanation.

Explanation:

Luke has a pencil 8 inches long, while Riley has a 3-inch long pencil.

So, first of all, who has the longer pencil?
It is Luke because he has a pencil 8 inches long while Riley has a pencil 3 inches long.

So, by how much is Luke's pencil longer that Riley's pencil?

If you take Luke's 8-inch pencil and place it by Riley's, you will see that Riley's is shorter. Then, if you use your ruler, you will see that Luke's pencil is longer by 5 inches.

Here is how you can show the calculations:

8-inch pencil (Luke's) minus 3- inch pencil (Riley's)= Luke's pencil is 5 inches longer than Riley's.

Hope this helps!
