Use the conversion ratio 1 foot equals 12 inches. A whiteboard is 7.5 feet long. How many inches long is the whiteboard? (1 point)
To find the length of the whiteboard in inches, we can use the conversion ratio of 1 foot equals 12 inches.
We have that the whiteboard is 7.5 feet long. Multiplying this by 12 will give us the length in inches.
7.5 feet * 12 inches/foot = 90 inches.
Therefore, the whiteboard is 90 inches long.
To find out how many inches long the whiteboard is, you can set up a proportion using the conversion ratio:
1 foot = 12 inches
We know that the whiteboard is 7.5 feet long, so we can set up the proportion as follows:
7.5 feet / x inches = 1 foot / 12 inches
To solve for x (the length of the whiteboard in inches), we can cross multiply:
7.5 feet * 12 inches = 1 foot * x inches
90 inches = x inches
Therefore, the whiteboard is 90 inches long.
To find out how many inches long the whiteboard is, we need to use the given conversion ratio that 1 foot equals 12 inches.
First, we need to set up a proportion to relate feet and inches:
1 foot / 12 inches = 7.5 feet / x inches
To solve for x, the number of inches, we can cross-multiply:
1 * x = 12 * 7.5
Simplifying the equation:
x = 90 inches
Therefore, the whiteboard is 90 inches long.
