1)tammy is making a poster. she had planned the poster to be 36 inches high and 24 inches wide. If she instead decides to make the poster 24 inches high, but keeps the same proportions, how wide will the poster be in inches?

my original answer was 12. But i tried again and i got 16. are any of these correct?

    16 is correct.

    I set up a proportion and cross multiplied.

    24/36 * x/24
    36x = 576
    x = 16

    36/24=24/x cross mulitply solve for x
    i get 16
