Answer 35 and 36 fully with the way you did it not only answer!!

35a. We're asked to compute the ratio between the enlarged width and the original width. So we literally perform the operation:
[tex]6.5\div 3.5 \approx 1.86[/tex]
35b. If the order is wrong the image would be shrunk instead of enlarged, with a ratio of [tex]3.5\div 6.5[/tex]
36. We know that
[tex]\dfrac{p}{q}=\dfrac{2}{3}[/tex]
Observe that
[tex]\dfrac{6p}{2q}=\dfrac{6}{2}\cdot\dfrac{p}{q}=3\cdot\dfrac{p}{q}=3\cdot\dfrac{3}{2}=\dfrac{9}{2}[/tex]
