Sally is drawing a map of her backyard. She plans to use the scale 1/2 : 3 feet.

If the actual distance between the tree house and the swing set is 24 feet, what should the distance on the scale drawing be? Round your answer to the nearest tenth of an inch if necessary.

Answer:

4in

Explanation:

You can use a proportion: 0.5in = x

---- -----

3ft 24ft

You are trying to find x (how many inches Sally would have to draw to represent 24ft.

Step one:Cross multiply( 0.5x24=12 and 3 times x =3x) After it will look like this: 3x=12

Step two: divide on both sides (the goal here is trying to get x and the answer by itself)

You should get x=4 **And boom shock-a-locka that's the answer :D
