Caranya 1 1/2+40%-0,3×1/9=

⇔1 1/2 + 40% - 0,3 × 1/9

⇔1/2 + 40/100 - 3/10 × 1/9

⇔1/2 + 40/100 - 1/10 × 1/3

⇔1/2 + 40/100 - 1/30

⇔1/2 + 2/5 - 1/30

⇔[tex] \frac{15 + 12 - 1}{30} [/tex]

⇔[tex] \frac{26}{30} = \frac{13}{15} [/tex]

[tex]1 \frac{1}{2} + 40\% - 0.3 \times \frac{1}{9} \\= \frac{3}{2} + \frac{2}{5} - \frac{3}{10} \times \frac{1}{9} \\ =\frac{15}{10} + \frac{4}{10} - \frac{1}{30} \\ =\frac{19}{10} - \frac{1}{30} \\= \frac{57}{30} - \frac{1}{30} \\ =\frac{56}{30} \\ = 1 \frac{26}{30} = 1 \frac{13}{15} [/tex]
caranya yang perkalian / pembagian dikerjakan terlebih dahulu

semoga membantu
