berapakah hasil dari 1 1 per 2+40%- 0,3:1 per 9

[tex]1 \frac{1}{2} + 40\% - 0.3 \div \frac{1}{9} \\ = \frac{3}{2} + \frac{2}{5} - \frac{3}{10} \div \frac{1}{9} \\ = \frac{3}{2} + \frac{2}{5} - \frac{3}{10} \times \frac{9}{1} \\ = \frac{3 }{2} + \frac{2}{5} - \frac{27}{10} \\ = \frac{3 \times 5 + 2 \times 2}{10} - \frac{27}{10} \\ = \frac{15 + 4}{10} - \frac{27}{10} \\ = \frac{19}{10} - \frac{27}{10} \\ = - \frac{8}{10} \\ = - 0.8[/tex]

Maaf Kalau Salah

Jawabanny:
= 3/2+2/5-3/10:1/9
= 3/2+2/5-3/10×9/1
= 3/2+2/5-27/10
= 3×5+2×2/10-27/10
= 15+4/10-27/10
= 19/10-27/10
= -8/10
= -0,8

JADIKAN JAWABAN TERBAIK YA SEMOGA MEMBANTU
