$frac{12}{5}$ = 1 + $frac{x}{1}$ + $frac{2}{1}$ + $frac{3}{4}$ ⇒Samakan Penyebut menjadi 4

$frac{12}{5}$ = ( $frac{1}{1}$ x $frac{4}{4}$ ) + ( $frac{x}{1}$ x $frac{4}{4}$ ) + ( $frac{2}{1}$ x $frac{4}{4}$ ) + $frac{3}{4}$

$frac{12}{5}$ = $frac{4}{4}$ + $frac{4x}{4}$ + $frac{8}{4}$ + $frac{3}{4}$

$frac{12}{5}$ = $frac{4}{4}$ + $frac{8}{4}$ + $frac{3}{4}$ + $frac{4x}{4}$

$frac{12}{5}$ = $frac{12}{4}$ + $frac{3}{4}$ + $frac{4x}{4}$

$frac{12}{5}$ = $frac{15}{4}$ + $frac{4x}{4}$

$frac{12}{5}$ – $frac{15}{4}$ = $frac{4x}{4}$ ⇒Samakan Penyebut menjadi 20

$frac{48}{15}$ – $frac{75}{15}$ = $frac{4x}{4}$

– $frac{27}{15}$ = $frac{4x}{4}$ ⇒4 dicoret dengan 4 menjadi 1

– $frac{27}{15}$ = x
