Question
If an earthworm is 18 mm long and it is photographed and the picture is magnified 2.5×, how long will it be in the picture?
Solution
Step 1: Identify the original length of the earthworm, which is 18 mm.
Step 2: Identify the magnification factor, which is 2.5 times.
Step 3: Multiply the original length of the earthworm by the magnification factor to find the length of the earthworm in the picture.
So, 18 mm (original length) x 2.5 (magnification factor) = 45 mm.
Therefore, the earthworm will be 45 mm long in the picture.
