hasil dari1,2÷80/100×8/9

1,2 ÷ 80/100 × 8/9
12/10 ÷ 80/100 × 8/9
12/10 × 100/80 × 8/9
disederhanakan dulu, jadi :
6/5 × 5/4 × 8/9
= 12/9
= 1 3/9
= 1 1/3

[tex] = 1.2 \div \frac{80}{100} \times \frac{8}{9} \\ = \frac{6}{5} \times \frac{100}{80} \times \frac{8}{9} \\ = 2 \times \frac{20}{10} \times \frac{1}{3} \\ = 2 \times 2 \times \frac{1}{3} \\ = \frac{4}{3} [/tex]
