\begin{gathered} Because\text{ we have to keep the rate of the picture we have that} \\ (11)/(8.5)=(7)/(x)\rightarrow x=(7\cdot8.5)/(11)=5.409 \\ \text{Now the new area is } \\ 7\cdot5.409\text{ =37.863} \\ \text{and if we want to reduce it to fit in a 5x7 fram we have} \\ 5\cdot7=35 \\ so\text{ the percent is} \\ (35)/(37.863)\cdot100=92.4 \end{gathered}
