Know the Answer?

Raquel Hicks · Answer 1

Answer: 70

The ratio of advertisement emails and normal emails is 7:10

So if 10 x 10=100, multiply 7 by 10 too so the values are equal

Kaydence Alvarez · Answer 2

Based on her 7/10 advertisements, you can predict 70/100 advertisements in the next 100 emails.

These are both ratios of 7/10.

The answer should be 70.
