Answer:
Step-by-step explanation:
Set this up as a proportion, with inches on the top and feet on the bottom for our scale. We will find the actual length first, then we'll find the width.
Cross multiply to get that the actual length is 5(2.5) = 12.5 feet. Now for the width:
Cross multiply to get that the actual width is 5(3) = 15 feet.
If you want the area of the room, multiply the length times the width to get
A = 15(12.5)
A = 187.5 feet squared

Answer:
-1 1/2 and -1 3/4 on the number line.
Step-by-step explanation:
First you find -1 on the number line. Then you add 1/2 which is also 2/4. You find it by going two places from -1 to the right.
Then you do the same for -1 3/4. You start at -1 and move 3 places to the right.
