Jeremy 2

Jeremy is digitally editing out some red-eye problems in the photos from his sister's birthday party. The eyes are small and hard to click on, so he zooms in on the photo from 100% to 400%. In the zoomed-in photo, the eyes are 3 cm wide. How many cm wide were the eyes before zooming?

Correct answer:

a =  0.75 cm

Step-by-step explanation:

r1=100%=100100=11=1 r2=400%=100400=14=4  b=3 cm  b = r2/r1   a  a=r2r1 b=41 3=41 3=43=0.75 cm
