Question

osephine noticed that out of 10 e-mails she received, 7 were advertisements. What can she predict about the number of advertisements she will receive in the next 100 e-mails? She will receive 7 advertisements. She will receive 10 advertisements. She will receive 70 advertisements. She will receive 90 advertisements.

Answer 1

She will receive 70 advertisements

Explanation:

With the information of 7 ads per 10 emails, the ratio is 7/10 emails being ads

If there is 100 emails, then both numbers will be multiplied by 10

7*10 = 70
10*10 = 100

The ratio is now 70/100

This means she will receive 70 advertisements per 100 emails
