1. A model of a skyscraper is made so that 1 inch represents 75 feet. What is the height of the actual building if the height of the model is 18 3/5 inches? *

Please help me with this question

1395 feet

Step-by-step explanation:

Given

1 inch = 75 feet

18 3/5 = y feet

Cross multiply

y x 1 = 18 3/5 x 75

Change mixed number to improper fraction

y = 93/5 x 75

Multiply through

= 6975/5

= 1395 feet

1395 feet

Step-by-step explanation:

What do we know?

1 inch represents 75 feet

Height of the model is 18 3/5 inches

First Step:

Alright so we know we need to multiply the 75 feet * 18  3 / 5 to find the real height .

Let's break it up into pieces and do it like this:

75*18   +     75* 3/5

1350  + 225/ 5

Second Step:

Now let's simplify!

1350 + 225/5 =

1350 + 45 =

1395

YA WE GOT THE ANSWE:

1395 feet
