Q. Spesial besok masuk sekolah (MPLS)

$frac{ cancel{78} : {}^{39} }{ cancel8 ^{2} } times frac{ cancel{92} : {}^{23} }{ cancel2} - frac{44}{5}$

$= frac{39 times 23}{2} - frac{44}{5}$

$= frac{897}{2} - frac{44}{5}$

ubah ke campuran

$= 2 frac{1}{2} - 8frac{4}{5} = (2 - 8) frac{5}{10} - frac{8}{10} \ \ = (2 - 8) frac{10 - 8}{10} = - 6 frac{2 : 2}{10 : 2} = bf - 6 frac{1}{5}$

Penjelasan dengan langkah-langkah:

78/8 × 92/2 – 44/5

= 39/4 × 46/1 – 44/5

= 39 × 46/4 × 1 – 44/5

= 1.794/4 – 44/5

= 897/2 – 44/5

= 4.485 – 88/10

= 4.397/10
