a beetle is 1.8cm long. A drawing of the beetle is made using a scale of 5:1. what is the length of the beetle in the map?
5 * 1.8 = ?
thank you so much ! i thought that was the answer but i wasn't sure :P
my answer is 0...

To find the length of the beetle in the map, we need to determine the scale factor and then calculate the scaled length.
The given scale is 5:1, which means that for every 5 units on the actual size, there is 1 unit on the map or drawing.
To find the scale factor, divide the actual length of the beetle by the length on the map:
Scale Factor = Actual Length / Map Length
In this case, the actual length of the beetle is 1.8 cm and the map length is unknown. Let's call it "x" for now.
Scale Factor = 1.8 cm / x
Since the scale is given as 5:1, the scale factor can also be expressed as 5/1.
Therefore, we can set up an equation using the two expressions for the scale factor:
1.8 / x = 5 / 1
Now we can solve for x by cross-multiplying:
1.8 * 1 = x * 5
1.8 = 5x
Divide both sides of the equation by 5 to isolate x:
1.8 / 5 = x
0.36 = x
So, the length of the beetle on the map is 0.36 units, where the units could be cm, inches, or any other specified measurement depending on the scale used.
