A flea is very difficult for the human eye to see. Jose looks at a drawing of a flea in a book.
The drawing uses the scale 5:1.
The actual length of a flea is 2 mm. How long is the drawing?
2/x = 5/1
...
To find the length of the drawing, we can set up a proportion using the given scale. The scale 5:1 means that for every 5 units on the drawing, it represents 1 unit in the actual length.
Let's assign variables:
Let L represent the length of the drawing.
Let A represent the actual length of the flea.
Using the given information:
L/A = 5/1
A = 2 mm
We can now substitute the known values into the equation:
L/2 = 5/1
To solve for L, we can cross-multiply and then divide:
L = (2 * 5) / 1
L = 10 mm
Therefore, the length of the drawing is 10 mm.
