A photograph is 6 centimeter wide 8 centimeter high. An enlargement of the photo has a height of 16 centimeters. Calculate the width of the enlargement

Because the proportions of the photo stay the same we can use cross multiplication, so 6/8=x/16, if we cross multiply we get 8x=16(6), which is 8x=96, solving for x we get 12
