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
Change 11 1/2 to 11 2/4, Then add. I'll be glad to check your answer.
To find the total length of the ribbon, you need to add the lengths of the two pieces of ribbon.
The first piece of ribbon is 6 1/4 feet long. To add it to the total length, convert the mixed number to an improper fraction:
6 1/4 = (6 x 4 + 1)/4 = 25/4
The second piece of ribbon is 11 1/2 feet long. Convert it to an improper fraction as well:
11 1/2 = (11 x 2 + 1)/2 = 23/2
Now, add the lengths of the two pieces of ribbon:
25/4 + 23/2 = (25 + 46)/4 = 71/4
Since the denominators are the same, you can simply add the numerators:
71/4 = 17 3/4
Therefore, the total length of the two pieces of ribbon is 17 3/4 feet.
