The unknown value became #15#

The trick hear is to realise that if you multiply by 1 you do not change the value. Example: #6xx1=6#

However, 1 is multifaceted, so we can alter something's appearance without altering its inherent worth.

#color(green)(5/6color(red)(xx1) color(white)("d") ->color(white)("d") 5/6color(red)(xx3/3)color(white)("d") =color(white)("d") (5xx3)/(6xx3)color(white)("d") =color(white)("d") 15/18#

To rewrite the expression ( \frac{5}{6} = \frac{?}{18} ), multiply both the numerator and denominator of ( \frac{5}{6} ) by 3:

[ \frac{5}{6} = \frac{5 \times 3}{6 \times 3} = \frac{15}{18} ]
