1. Write the ratios of the price paid per number of photos purchased for each store.

1. Write the ratios of the price paid per number of photos purchased for each store.
100/12 = 25/3
120/18 = 20/3
2. Do the ratios form a proportion? Explain.
No, the ratios do not form a proportion. To test this, I cross multiplied the two simplified ratios and the two sides were not equal to one another.

Answer 1

25/3 = 20/3
25*3 = 20*3
75 = 60
This false statement that proves that the ratios are not equal.
