Magnification can be calculated using the equation: magnification=size of image/actual si specimen. A bacterial cell is 0.003mm long. A magnified image of the cell is 21mm long. The magnification of the image is x __

## Step 1: Conversion of unitsThe size of the bacterial cell is given in millimeters (mm), while the size of the magnified image is also given in millimeters (mm). Therefore, there is no need to convert units in this case as both are in the same unit.## Step 2: Calculation using formulaThe formula to calculate magnification is: ### Substitute the given values into the formula:###
