Bernadette bought two pieces of ribbon. One piece is 6 1/4 feet long, and the other is 11 1/2 feet long. Find the total length of the ribbon. And I need a typing answer please.

Not sure what you mean by

And I need a typing answer please.

But,
6 1/4 + 11 1/2 = 17 3/4

It is an essay question.

hmmm. Not sure how to write an essay on how to add two mixed numbers. But google probably has several discussions on how to handle things.

ooooh thanks

To find the total length of the ribbon, you need to add the lengths of the two pieces together.

The first piece of ribbon is 6 1/4 feet long, which can also be written as 6.25 feet.
The second piece of ribbon is 11 1/2 feet long, which can also be written as 11.5 feet.

To calculate the total length, add the two lengths together:

6.25 + 11.5 = 17.75 feet

Therefore, the total length of the ribbon is 17.75 feet.
