MS. SUE WHAT SCHOOL DO U WORK AT????

Here's another way to approach this problem.

1/2 inch = 10 ft.
1 inch = 20 ft.

3/4 * 20 = 15 feet

I'm retired.

ok thank u got it more but can u help me on other problems they r the same but different #'s

If I have different fractions can I multiply the others by 20 as well?

To figure out the actual width of the living room using the blue print scale, you'll need to use the scale conversion ratio. In this case, the scale is 1/2 inch = 10 feet.

Here's how to calculate it:

1. Determine the given distance on the blueprint, which is 3/4 inches.
2. Set up a proportion using the scale ratio. Place the given distance over the known distance and set it equal to x over the actual width.

(3/4 inches) / (1/2 inch) = x / actual width

3. Simplify the proportion by cross-multiplying.

(3/4) * (2/1) = x

(6/4) = x

4. Calculate the actual width by simplifying the proportion.

x = (6/4)
x = 1.5

The actual width of the living room is 1.5 feet.

One way to figure it out is to let x = the actual width. Cross multiply and solve for x.

(1/2) / 10 = (3/4) / x

30/4 = (1/2)x
(30/4)/(1/2) = x
(30/4) * (2/1) = 60/4 = 15 feet
