a photograph now measures 33cm wide by 45 cm long. before it was enlarge its width was 11cm what equation represents this proportion

33/45 = 11/x

33/45 = 11/x

To represent the proportion of the photograph's width before and after enlargement, we can set up the following equation:

Before Enlargement: Width (before) / Length (before) = Width (after) / Length (after)

Let's assign variables for the measurements:
- Width (before): x cm
- Length (before): Unknown (let's say y cm)
- Width (after): 33 cm
- Length (after): 45 cm

Now we can write the equation:

x / y = 33 / 45

This equation represents the proportion of the photograph's width before and after the enlargement.
