Answer:
The new photo is not proportional.
Step-by-step explanation:
The original dimensions of the photograph was 5 inches by 7 inches.
The new dimensions of the photograph is 25 inches by 30 inches.
We want to know if the enlarged photograph is proportional to the original photo.
If the new image is proportional, than the ratio of the new width to length must be equivalent to the ratio of the old width and length.
For the old photograph, the ratio of the width to the length is 5/7 or 5:7.
For the new photograph, the ratio of the width to the length is 25/30.
We can simplify this by dividing both layers by 5 to acquire 5/6 or 5:6.
Since 5/6 is not equal to 5/7, the new photo is not proportional to the old.
