Given:

\(\displaystyle\triangle{M}LN,\overline{{{M}{L}}}={13},\overline{{{M}{N}}}={6},\overline{{{N}{L}}}={10},\triangle{R}{Q}{S},\overline{{{R}{Q}}}={39},\overline{{{R}{S}}}={18},\overline{{{S}{Q}}}={30}\)

Find the scale factor from \(\displaystyle\triangle{M}LN\) to \(\displaystyle\triangle{R}{Q}{S}\).
