Question

7. A photograph negative measures 15 inches by

Answer 1

Answer:

First we need to set a proportion

Currently the negative measures 15 inches by 2 inches. And the longer dimension of the printed version is 4 inches. Therefore:

$\frac{2}{y} = \frac{15}{4}$

$15y = 8$

$y = 0.5333$

Therefore, the dimension of the shorter dimension is 0.5333.
