## How can you determine the aspect ratio of a picture frame that measures 12 3/4 inches long and 8 1/2 inches wide?

To determine the aspect ratio of a picture frame that measures 12 3/4 inches long and 8 1/2 inches wide, follow these steps:

1. Begin by converting the mixed fractions into improper fractions for easier calculations.

- 12 3/4 inches can be converted to (4 * 12 + 3) / 4 = 51/4 inches.

- 8 1/2 inches can be converted to (2 * 8 + 1) / 2 = 17/2 inches.

2. Next, find the greatest common divisor (GCD) of the two improper fractions to simplify them if needed.

- The GCD of 51 and 4 is 1.

- The GCD of 17 and 2 is also 1.

3. Divide both improper fractions by their respective GCD.

- 51/4 divided by 1 is 51/4.

- 17/2 divided by 1 is 17/2.

4. The resulting fractions represent the aspect ratio of the picture frame. In this case, the aspect ratio is 51/4 to 17/2.

5. To make the aspect ratio more easily interpretable, you can multiply both fractions by the same number to get a whole number aspect ratio. For example, multiplying both fractions by 4 gives a ratio of 204:34.

Therefore, the aspect ratio of the picture frame that measures 12 3/4 inches long and 8 1/2 inches wide is 204:34.

## How can a 1/8-inch scale be used to represent a 32-foot long object? Can you provide an example?

To use a 1/8-inch scale to represent a 32-foot long object, you would need to scale down the actual length of the object to fit the scale. Here\'s an example of how this can be done:

Step 1: Understand the scale ratio

A 1/8-inch scale means that every 1/8 inch on the scale represents a specific length in real life. In this case, we need to determine what length in real life corresponds to 1/8 inch on the scale.

To find this, we can set up a ratio:

1/8 inch (on the scale) = x inches (in real life)

Step 2: Determine the length on the scale

Now, we know that the scale represents a 32-foot (which is equal to 384 inches) long object. We can use the ratio from step 1 to determine how long that object would be on the scale.

Let\'s solve for x:

1/8 inch (on the scale) = x inches (in real life)

Multiply both sides of the equation by 384 (the length of the object in inches):

384 * (1/8) inch (on the scale) = 384 * x inches (in real life)

Simplifying this equation gives us:

48 inches (on the scale) = 384 * x inches (in real life)

Divide both sides of the equation by 384:

48 inches / 384 inches = x

Simplify this fraction gives us:

1/8 = x

So, 1/8 inch on the scale represents 1/8 inch in real life.

Step 3: Apply the scale to the object

Now that we know the scaling ratio, we can use it to represent the 32-foot long object on the scale. Since 1/8 inch on the scale represents 1/8 inch in real life, we can simply measure 1/8 inch on the scale and mark it as the length of the object.

For example, on a ruler or measuring tape with the 1/8-inch scale, you would find the 1/8 inch mark and use it as the length for the object. In this case, the 1/8 inch mark would represent 32 feet in real life.

By applying the scaling ratio consistently throughout the object, you can accurately represent the full length of the 32-foot object on the 1/8-inch scale.

It\'s important to note that when working with scales, the units of measurement need to be consistent. In this example, we assumed that both the scale and the object\'s length were in inches, but the same principles can be applied to any unit of measurement.

## How do you translate the fraction 1/8 inch into inches on a scale? For example, what does the 1/2 mark equal?

To translate the fraction 1/8 inch into inches on a scale, you need to understand how the scale is set up. Typically, scales are used to represent larger measurements in smaller increments.

In this case, let\'s assume that the scale is set up in such a way that 1/8 inch on the scale represents a certain length in real life.

To find out what the 1/2 mark on the scale equals, you would need to know the length that the entire scale represents. Once you have that information, you can divide it by 8 to determine how much length each increment on the scale represents.

For example, let\'s say the entire scale represents 32 feet. Since there are 12 inches in a foot, the total length represented by the scale would be 384 inches.

To find out how much length each increment on the scale represents, you would divide 384 inches by 8 (the number of increments) to get 48 inches.

Therefore, each increment on the scale would represent 48 inches. The 1/2 mark on the scale would equal 1/2 of 48 inches, which is 24 inches.
