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?
five times two millimeters is ten millimeters which is one centimeter
Two millimeters is just a dot really, you would not be able to tell it was a flea very well. One centimeter is a size where you would see head and legs and stuff easily :)
To find the length of the drawing, we can use the concept of ratios and proportions.
Given that the scale of the drawing is 5:1, this means that for every 5 units on the drawing, it represents 1 unit in real life. In other words, the drawing is scaled down by a factor of 5.
To find the length of the drawing, we can set up the following proportion:
(Length of the drawing) / 1 = (Actual length of the flea) / (Scale factor)
Let's plug in the given values:
(Length of the drawing) / 1 = 2 mm / 5
We can simplify the proportion:
(Length of the drawing) = (2 mm / 5) * 1
(Length of the drawing) = 2 mm / 5
To calculate the actual length of the drawing, we divide 2 mm by 5:
(Length of the drawing) ≈ 0.4 mm
Therefore, the length of the drawing of the flea is approximately 0.4 mm.
