Which formula gives the correct method for calculating the actual size of an object?
- A$\text{actual size} = \frac{\text{magnification}}{\text{image size}}$
- B$\text{actual size} = \frac{\text{image size}}{\text{magnification}}$
- C$\text{actual size} = \text{image size} \times \text{magnification}$
- D$\text{actual size} = \text{image size} - \text{magnification}$
