Final answer:
Janie used
or
yards of ribbon for her bookmarks.
Step-by-step explanation:
To find out how many yards of ribbon Janie used for her bookmarks, we need to multiply the total yards of ribbon she has
by the fraction of ribbon she used (1/2). To multiply fractions, we multiply the numerators (the numbers on top) and the denominators (the numbers on the bottom).
So, (2 + 3/4) × 1/2
= 11/4 × 1/2
= 11/8
= 1 + 3/8.
Therefore, Janie used (1 + 3/8) yards of ribbon for her bookmarks.
