-1/2 x 7/5/70 tolong di bantu ya...

-1/2 x 7/5 x 1/70
= -1/2 x 7/350
= -7/700
= -1/100

maaf jika salah, semoga membantu

[tex] - \frac{1}{2} \times \frac{ \frac{7}{5} }{70} \\ = - \frac{1}{2} \times \frac{7}{5} \div 70 \\ = - \frac{7}{10} \div \frac{70}{1} \\ = - \frac{7}{10} \times \frac{1}{70} \\ = - \frac{1}{10} \times \frac{1}{10} \\ = - \frac{1}{100} [/tex]

Maaf Kalau Salah
