# A document that is 30in x 40 in is redrawn 1 1/2 scale and redrawn again at a 1/2 scale. What are the final dimensions?

On this i have no clue what to do.

## 30 * 1.5 = 45

45 * .5 = 22.5

Do the same with the other side.

## 22.5 by 30

## To find the final dimensions after redrawing the document at a scale of 1 1/2 and then at a scale of 1/2, follow these steps:

Step 1: Convert the fractions to decimals.

1 1/2 can be written as 1.5, and 1/2 is equivalent to 0.5.

Step 2: Calculate the dimensions after scaling up by 1 1/2.

To determine the new dimensions after scaling up by 1 1/2 (1.5), you need to multiply each side's length by the scale factor.

New length = 30 in x 1.5 = 45 in

New width = 40 in x 1.5 = 60 in

So, after scaling up by 1 1/2, the dimensions become 45 inches x 60 inches.

Step 3: Calculate the dimensions after scaling down by 1/2.

To determine the new dimensions after scaling down by 1/2 (0.5), you need to multiply each side's length by the scale factor.

New length = 45 in x 0.5 = 22.5 in

New width = 60 in x 0.5 = 30 in

So, after scaling down by 1/2, the final dimensions become 22.5 inches x 30 inches.

## To find the final dimensions of the document, we need to follow these steps:

Step 1: Start with the original dimensions of the document, which are 30 inches by 40 inches.

Step 2: To determine the dimensions at 1 1/2 scale, multiply both the length and the width of the original dimensions by 1 1/2 (or 3/2).

30 inches x 1 1/2 = 45 inches (new length)

40 inches x 1 1/2 = 60 inches (new width)

So, at the 1 1/2 scale, the dimensions are 45 inches by 60 inches.

Step 3: To find the final dimensions at the 1/2 scale, we multiply the dimensions at the 1 1/2 scale by 1/2.

45 inches x 1/2 = 22.5 inches (final length)

60 inches x 1/2 = 30 inches (final width)

Therefore, the final dimensions of the document after being redrawn at the 1/2 scale are 22.5 inches by 30 inches.
