    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.

    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
