To determine how long the remaining piece of ribbon is after trimming off 12 of a yard from a total of 45 of a yard, we first need to calculate the amount of ribbon remaining.
-
Convert 45 of a yard to a fraction:
- Assuming you meant 45 as a fraction, it should be written as 45/1. (Please clarify if it's intended to be a number or fraction.)
-
Trim off 12 of a yard:
- If 12 is considered as a fraction, it should also be expressed in terms of yards as 12/1. (Again, please clarify if it's meant to be different.)
-
Perform the subtraction: \[ \text{Remaining Ribbon} = \frac{45}{1} - \frac{12}{1} = \frac{45 - 12}{1} = \frac{33}{1} \] So, it results in 33 of a yard remaining.
If the values 45 and 12 corresponded in terms of fractions of a whole yard (e.g., 45/100 or 12/100), you'd adjust the calculation accordingly.
Since your responses include options such as 1 yard, 3/10 yard, 1/2 yard, and 1 and 12/15 yard, perhaps your initial values are intended to represent a fraction of yards that was misunderstood in the transcription (like labeling 45/100 as just 45). Please clarify your intended fractions for accurate calculations!
If those numeric forms represented specific values, we can't make any assumptions. In loose fractions, let’s add precision to your inquiry.
