Question 1012948
.
A 8 in. by 10 in. photo is reduced so that the width (the shorter dimension) is 3 in. What is the length of the reduced photo?
--------------------------------------------------------------


I believe everybody agree that the photo was reduced proportionally.


So, use the proportion


{{{8/10}}} = {{{3/x}}}.


Now you can find the unknown length x of the reduced photo from the proportion as x = {{{(10*3)/8}}} = {{{30/8}}} = {{{3}}}{{{3/4}}} in.
