For every 50 emails that nick sent in a month, he received 30 emails. what is the ratio in simplest form of the number of emails sent to the number of emails received by nick that month? a.5: 2 b.3: 5 c.2: 5 d.5: 3

The answer is D. Because, for every 50 emails dent he received 30 back in response. So, let 5 represent the emails he sent and let 3 represent the emails received... so your answer should be D: 5:3.

I hope this helps :D
