1 2/5 dikurang 1 4/5 dibagi 0.75 dikali 75% .......berapa jawaban dalam bentuk pecahan biasa ?

Mapel : Matematika
Bab : Operasi Hitung Pecahan

1 2/5 - 1 4/5 : 0,75 x 75%
= 7/5 - 9/5 : 75/100 x 75/100
= 7/5 - 9/5 x 100/75 x 75/100
= 7/5 - 9/5 x 1/1
= 7/5 - 9/5
= -2/5

[tex]1 \frac{2}{5} - 1 \frac{4}{5} \div 0.75 \times 75\%[/tex]
[tex]1 \frac{2}{5} - 1 \frac{4}{5} \div (0.75 \times 75\%) = [/tex]
[tex]\frac{7}{5} - \frac{9}{5} \div ( \frac{75}{100} \times \frac{75}{100} )[/tex]
[tex] \frac{ 7}{5} - \frac{9}{5} \div ( \frac{3}{4} \times \frac{3}{4} )[/tex]
[tex]\frac{ 7}{5} - \frac{9}{5} \div \frac{9}{16} [/tex]
[tex] \frac{7}{5} - ( \frac{9}{5} \times \frac{16}{9} )[/tex]
[tex] \frac{7}{5} - \frac{16}{5} [/tex]
[tex] \frac{ - 9}{5} [/tex]
