The correct response that describes three ways to write the ratio comparing 4 electronic devices for every 3 people is:
4 to 3, 4:3, 4/3
This indicates the ratio of electronic devices to people can be expressed as:
- "4 to 3" (word form)
- "4:3" (colon form)
- "4/3" (fraction form)
(Note: "34" and "43" are not correct representations of the ratio in any standard format.)
