Final answer:
Shelby needs 1 more yard of fabric to create her skirt because she has 6 yards and requires 7 yards in total. The calculation is based on a subtraction: 7 yards - 6 yards = 1 yard.
Step-by-step explanation:
The question asks us to determine how many more yards of fabric Shelby needs to make her skirt. To find the answer, we need to perform a simple subtraction operation because Shelby has a certain length of fabric and needs a specific total length for her project.
Shelby needs 7 yards of fabric in total and already has 6 yards. To calculate how many more yards she needs, we subtract the length she has from the total length required:
7 yards (total needed) - 6 yards (length Shelby has) = 1 yard
Therefore, Shelby needs 1 more yard of fabric to make her skirt.
This kind of calculation is similar to other everyday scenarios, such as measuring the length of a garden or converting measurement units like yards to feet or inches, determining volumes for cooking recipes, or calculating real distances from a scaled map.
