How to do a scale in 6th grade? begging

You have to convert it first, and you first list the formula: scale = distance on the map actual distance, actual distance = distance on the map scale, distance on the map = scale bar actual distance. You write according to the formula, add the conversion, 1 centimeter on the map, equal to 100 kilometers of the actual distance, = 1 100000, and so on.

The default unit of the scale bar is centimeters. Scale bar = distance on the graph actual distance, distance on the graph = scale bar actual distance, actual distance = scale bar distance on the map. Don't forget to convert units!

Scale bar = distance on the graph Actual distance.

Actual distance = distance on the graph scale.

Distance on the graph = scale bar actual distance.

It's very simple, first look at how much, for example, 1 to 2000, give you 20 meters, about points, remember that the unit of the scale is the unit of the same level. Not quite, I don't know what to say.

Next, write according to the formula, scale distance on the map actual distance, actual distance distance on the map scale, distance on the map scale actual distance. The rest is up to you.

Please complete the question.

Scale Distance on the graph Actual distance Distance on the graph Scale bar Actual distance Actual distance Distance on the graph Scale bar 1 cm on the graph represents the actual distance of 100 cm.

The product of the inner term is equal to the product of the outer term.

The contents of the sixth grade mathematics scale stool with ruler are as follows:

1. The scale bar is the ratio of the length of a line segment on the diagram to the actual length of the corresponding line segment on the ground.

2. The scale formula is: scale bar = the ratio of the distance on the graph to the actual distance. There are three ways to represent loose and coarse: numerical scale, pictorial scale, and text scale.

3. The content of the large-scale map is detailed and the geometric accuracy is high, which can be used for measurement on the map. The content of small-scale maps is highly generalized, and it is not suitable for measurement on the map.

1 All (1) 40000000 cm = 400 km, he said that 1 cm on the map represents the actual distance of 400 km, draw a line segment on the map, you can draw 3 cm long, then each cm represents 400 km, (2) 1800 km = 180000000 cm, 3 cm: 180000000 cm = 1: 600000000, (3) 120 km = 12000000 cm, scale:

3: 12000000=1:4000000, the line segment scale is the same as the first question, (4) one centimeter on the figure represents the actual distance of 5 kilometers, 5 kilometers = 500,000 centimeters, numerical scale:

1:500000, actual distance = distance on the map Scale, : 500000) = 2100000 cm = 21 km, (5):

2000000) = 5000000 cm = 50 km.
