Taylor measures the length of two ribbons, Ribbon A and Ribbon B. The length of Ribbon A is 2 feet. The length of Ribbon B is 28 inches. Which ribbon is shorter? Explain.
Understand the Problem
The problem states that Taylor measured two ribbons called Ribbon A and Ribbon B. Ribbon A is measured at 2 feet, and Ribbon B is measured at 28 inches. We need to determine which ribbon is shorter, this can be done by converting both measurements to the same unit and then comparing the values.
Answer
Ribbon A is shorter. Ribbon A is 24 inches and Ribbon B is 28 inches. $24 < 28$.
Answer for screen readers
Ribbon A is shorter. Ribbon A is 24 inches and Ribbon B is 28 inches. $24 < 28$.
Steps to Solve
- Convert feet to inches
To compare the lengths of the two ribbons, we need to convert them to the same unit. We know that 1 foot is equal to 12 inches. Therefore, we can convert the length of Ribbon A from feet to inches by multiplying by 12.
$2 \text{ feet} \times 12 \frac{\text{inches}}{\text{foot}} = 24 \text{ inches}$
- Compare the lengths
Now we have the lengths of both ribbons in inches. Ribbon A is 24 inches long. Ribbon B is 28 inches long. Comparing these values, we see that 24 is less than 28.
- Determine the shorter ribbon
Since Ribbon A is 24 inches and Ribbon B is 28 inches, Ribbon A is shorter.
Ribbon A is shorter. Ribbon A is 24 inches and Ribbon B is 28 inches. $24 < 28$.
More Information
There are 12 inches in a foot.
