Find the scale ratio for the map described below. 1 mm (map) equals 500 m (actual) The scale ratio is 1 to nothing.

1:500000

Step-by-step explanation:

1 mm (map) equals 500 m (actual) .

Let's convert 500 m to mm.

1m = 1000mm

500m = 500000 mm

So 1mm to 500000mm on a scale is

1:500000

So it's all about converting the metre to million metre then doing the ratio.

In this case we are not to divide anything because it's already in 1.

So it's 1mm on paper then 500000mm on actual.

Thank you

1km=1000m

so 4.5(1000m)/90m

4500m/90m,we eliminate meter by meter

,4500/90=50
