Question 770520
If you want to reduce the size without distorting it (keeping the proportions),
the proportion {{{Y/91=16/69}}} will give the height {{{Y}}} in inches for a 16 inch width.
{{{Y/91=16/69}}} --> {{{Y=16*91/69}}} --> {{{Y=21.1}}}(rounded to the nearest inch) or {{{Y=21.1}}}(rounded to the nearest tenth of an inch)
